Cyclops portable infrared thermometers set new high temperature standard

Cyclops 100 portable infrared thermometer Cyclops portable infrared thermometers have been setting the industry standard for non-contact temperature measurement of high temperature targets for over two decades and the new Cyclops 100 portable infrared thermometers from temperature specialists Land Instruments International move that industry standard higher.

Two models are available - Cyclops 100 and Cyclops 100B. Both thermometers provide wired RS232C serial communications. The Cyclops 100B also features enhanced connectivity using user-friendly Bluetooth wireless communications.

These innovative new hand-held thermometers use the latest digital signal processing techniques to provide fast, reliable, precision temperature readings within the range 550 to 3000C.

Flexible configuration and the simple, language-independent, Icon-driven menu system make the C100 extremely user friendly.

The bright, backlit external multi-function graphics panel provides an indication of thermometer status and configuration together with simultaneous displays of continuous, average, peak and valley temperatures. The user-selected mode of temperature is also displayed in the viewfinder.

The precision reflex optical system gives a narrow field of view (180:1, to 98% energy) permitting clearly defined measurement of high temperature targets as small as 4.8mm at 1m distance. Targets as small 0.4mm diameter can be measured using optional close-up lenses.

The short operating waveband (1.0 micron), with advanced spectral filtering, has been carefully chosen to minimise errors due to uncertainty in emissivity and the effects of atmospheric vapour components.

With an extended emissivity compensation up to 1.20 Cyclops 100 can be programmed to provide reflectivity compensation for measuring targets in hotter surroundings.

Choice of data logged outputs is provided. C100 offers classic, historical and burst mode (up to 35 readings/second) data logging to the optional DL-1000 Data Logger software via a wired connection to HP iPAQ or PC/laptop. The C100B provides the addition of Bluetooth wireless data logging to DL-1000.

Cyclops 100 can provide the user with numerous benefits including: no contamination, interference or damage to the process or material; aids product quality control, maximizes production rates and fuel efficiency.

Cyclops 100 is ruggedly designed, ideal for use in steel, glass, refractories, heat treatment, semi-conductors and many more applications.

NEW RUGGED INFRARED THERMOMETER TAKES EVERYDAY KNOCKS IN THE PRODUCTION LINE

Monitoring human body temperature The new RT8A infrared thermometer from Land Instruments International is sturdily built to withstand the rigours of measuring the temperature of moving materials, webs or inaccessible objects without contact in hostile production environments.

Measuring product temperature in this way can improve quality, conserve energy, and optimise production rates without contaminating, damaging or interfering with the process or material.

Encompassing four models covering operating temperatures from 0 to 500C/
0 to 1000F, the two wire stand-alone RT8A range of infrared thermometers is suitable for a wide variety of primary OEM and end-user applications in industries as diverse as asphalt, mineral processing, glass, food, paper, converting, plastics, printing and textiles.

The protection afforded by the robust, IP65/NEMA 4X rated housing can be supplemented by optional cooling and lens purging facilities when required.

A comprehensive choice of mounting and protection accessories from the well-proven System 4 range makes it easy to install the thermometer at the optimum point in the process.

RT8A thermometers are designed to be integrated directly into a simple two-wire 4 to 20mA current loop for measuring, monitoring or control purposes.
Accurate, reliable and stable temperature measurement is assured by the RT8A's response time, which is adjustable from 1 to 10s; accuracy within <0.5% of span; and minimal drift with change in ambient temperature of <1.5C per 10C.

For further information see the RT8A thermometer

Top of page THE LATEST IN MEASURING ROADSTONE PRODUCTION TEMPERATURES

Roadstone Plant - temperature measurement using RT8A The new rugged RT8A infrared thermometer from Land Instruments International is the company's latest product for monitoring roadstone temperature throughout the production process to ensure product quality and minimise energy costs.

The outcome of over 25 years' experience of the roadstone industry, the stand-alone RT8A range of infrared thermometers encompasses four models covering temperatures from 0 to 500C/0 to 1000F.
A comprehensive choice of mounting and protection accessories from the well-proven System 4 range makes it easy to install the thermometer at the optimum point in the process.

RT8A can then be integrated directly into a simple two-wire 4 to 20mA current loop with low cost indicators, controllers and recorders for measuring, monitoring or control purposes.

The protection afforded by the robust, IP65/NEMA 4X rated housing can be supplemented by optional cooling and lens purging facilities when required.

Accurate, reliable and stable temperature measurement is assured by the RT8A thermometer's response time, which is adjustable from 1 to 10s; accuracy within <0.5% of span; and minimal drift with change in ambient temperature of <1.5C per 10C.

At all points of the manufacturing process, the RT8A infrared thermometer is a superior alternative to thermocouples, which are soon damaged and worn by contact with the product, respond too slowly and introduce lags into the system that result in poor control.

At the drier exit chute, the thermometer sights onto a stream of aggregate. The RT8A output can be used to indicate aggregate temperature, or utilised in a closed loop control system to control the burner, thus minimising fuel wastage and maximising efficiency whilst controlling aggregate temperature.

During mixing, the batch nature of the process precludes automatic burner control - but knowledge of the hot stone temperature in the batch heater and its subsequent effect on binder and filler temperature is a useful aid to process control.  Once in the mixer, the temperature of the material cannot be adjusted; but again, measurement at this point permits rejection of a single batch if it falls outside temperature specification limits, avoiding contamination of acceptable material.

Similarly, installing an RT8A thermometer at the mixer exit sighted onto the stream of coated roadstone as it falls from the mixer/storage bin into the delivery vehicle provides a final opportunity to reject out-of-specification product.

Temperature control is especially critical in continuous-production, drum-mix asphalt plants, where even slight fluctuations in final mix temperature can result in large volumes being rejected.
In this situation, the RT8A thermometer is mounted to sight on the stream of coated material as it leaves the discharge chute prior to the elevator system.  The thermometer output can also be fed into a chart recorder, or used to control an automatic burner control system.

RESPONDING TO THE AVIAN FLU PANDEMIC THREAT WITH LAND THERMAL IMAGERS

Monitoring human body temperature Following the growing threat of a flu pandemic and increasing number of fatalities from avian flu, the World Health Organization (WHO) has issued a warning calling for heightened monitoring and surveillance for cases and welcomed initiatives on epidemiologic investigation.

Since 2004, human cases of avian flu resulting in death have been reported from Vietnam, Thailand, Cambodia, and Indonesia. Poultry outbreaks were also reported in Malaysia and Laos.

During 2005, outbreaks among poultry have so far been confirmed in Cambodia, China, Indonesia, Kazakhstan, Mongolia, Romania, Russia, Thailand, Turkey, and Vietnam.

Land Instruments International - one of the world's leading specialists in non contact temperature measurement and infrared thermal imaging - developed a dedicated Human Body Temperature Monitoring System HBTMS which was used successfully for mass screening in public places, such as airports, ports and terminals, following the need to restrict the spread of the deadly SARS outbreak in 2003.

The use of Land's Human Body Temperature Monitoring System HBTMS is just one of the measures which can help minimize global public health risks that could arise from large outbreaks of highly pathogenic avian flu.

The non contact system is simple and easy to set up and operate. It is non-invasive and can assist in monitoring and detecting a significant rise in the skin surface temperature (usually the face), which is typically associated with a person running a high fever.

The HBTMS system is based around a miniature, on-line thermal imaging camera system - the FTI Mv. The ruggedised, compact version - the FTI Mini can also be used as part of the system.

These imagers use the latest uncooled Microbolometer detector technology with a unique combination of high performance, ruggedness, small size and affordable price.

The FTI Mv and FTI Mini are complemented by the application specific Human Body Temperature Monitoring software system, the latest of Land's successful PC-based range of thermal image processing software systems, which provides alarms when a set temperature threshold has been triggered.

The thermal imaging system provides a thermographic image of human body temperatures (typically the face) at a distance and compares it with that of an extremely precise blackbody calibration source at high speed - 30 fps - to provide a highly accurate measurement of body temperature.

The system is reliable and highly accurate, attained uniquely with the use of a certified temperature calibration source to provide a level of accuracy unparalleled by other, existing thermal imaging equipment.

The powerful combination of the thermal imager, temperature reference source and image processing software system HBTMS is ideal for a wide range of cost effective, highly efficient mass screening applications.

Top of page INFRARED THERMOMETER KEEPS A CHECK ON INCINERATOR TEMPERATURES

The new non contact CDA incinerator thermometer The new non contact CDA incinerator thermometer from Land Instruments International is a reliable means of determining the temperature of the atmosphere in waste incinerators.
The incinerator thermometer "sees through" cold CO2 to measure the hot atmosphere beyond, is insensitive to the presence of gases other than CO2 and relatively insensitive to particulate matter in the atmosphere - characteristics that collectively ensure that it measures the true gas temperature.

As a rough guide, good measurements are possible for temperatures above 600C, at CO2 concentrations above 4% and for path lengths of a few metres. At higher temperatures, lower concentrations and/or shorter paths can be measured. The overall temperature measurement range is 400 to 1800C / 750 to 3270F.

The Land CDA incinerator thermometer can also measure gas or flame temperature in a variety of other plant situations, provided there is a sufficient CO2 concentration at high temperature combined with sufficient path length.

In an incinerator, the non contact CDA thermometer can be pictured as an "invisible thermocouple" extending into the atmosphere above the bed by around 2m/6ft (penetration depth depends on atmosphere conditions). In reality it is fitted wholly on the outside of the incinerator, usually to a flanged tube that penetrates the wall.

To ensure secure thermometer installation and adequate protection at the optimum position on the process, the instrument is compatible with the standard Land mounting accessories. The thermometer protection jacket can be air or water-cooled, and the sighting tube must normally be air-purged. Ambient temperature limits are 0 to 50C / 32 to 122F.

A simple 2-wire loop connection outputs a 4 to 20mA signal linear in temperature.

SMALLEST HAND HELD THERMAL IMAGER IN THE WORLD IS BIG ON BENEFITS

Land Guide M4 Thermal Imager The mobile phone-sized Land Guide M4, the world's smallest, lightest and most advanced yet thermal imager is now available from Land Instruments International.

Incorporated into the low-cost, compact design are advanced features such as fingertip controls, high quality thermal and visual images with voice annotation, on-board image processing, a large capacity memory and versatile USB connectivity.

With a sensitivity of 0.12C, the Guide M4 detects extremely small temperature differences within the measurement range -20 to 250C and displays them as high-resolution, 16-bit thermal images.

The link with the target object is made by the high quality digital images captured by the built-in visual camera, and a built-in laser locator that helps to pinpoint hot spots.

To simplify the identification of potential problems, there are four measurement modes - simultaneous four-spot and four-area analysis, line profile and isotherm analysis - all of which can be saved as images.

The position and temperature of the hottest spot within the image is automatically tracked and indicated by a cursor, and a second cursor in the image centre is used to indicate the temperature and provide a reference for inspection analysis.

An audible alarm is activated when the measured temperature exceeds a pre-set value.

The Guide M4 has a 1Gb memory for recording and on-board storage of over 5,000 files, each of which can include a thermal and visual image with voice annotation.

Completing the package is a Windows-based post-processing software program, which offers an extensive range of temperature measurement, image processing and report generating functions.

Top of page THERMAL IMAGING SYSTEM DETECTS STEEL SLAG

Slag detection system - SDS The new SDS slag detection system from Land Instruments International combines the latest thermal imaging technology and almost 60 years' experience of the steel industry to control slag carry-over from furnace to ladle.

Once the system hardware is installed in a suitable position to view the tapping area, the pre-installed and configured image processing software works 'straight out of the box' with minimum set-up - a feature not available with any other system.

The operator has access to all the data for quality control purposes, and can view critical information such as the live thermal image, steel and slag percentages, time versus percentages graph, alarm level and alarm status. Secondary information such as tap number and sensor temperature is also available, but is less prominent so as not to distract the operator during the tap.

SDS records each tap and simultaneously generates a log and graph of the steel/slag data. When a pre-set percentage of slag or steel is detected within the defined window, an alarm is generated to stop the tap and the video, text and graph files are saved and identified by tap number for later analysis.

There are a number of interconnectivity options for on-line control, and tap data is automatically recorded in three forms for post analysis and future process improvement. In addition, up to four users can view remotely a condensed view of the live tap anywhere on the plant.

Inputs and outputs from the steel plant and slag detection system include digital output, DDE, OLE, Ethernet and OPC. Data to the SDS includes tap number, alarm level and five unique user-specified variables, such as charge number, heat number, steel grade and tap temperature.

The SDS software system has been purpose-designed to provide steel plant engineers with the tools to develop and improve the transfer of steel from one process to another.

The SDS camera uses a focal plane array microbolometer with a temperature measurement range of 600 to 2000 degrees C and a thermal image resolution of 320 x 240 pixels. Its operating wavelength is 3.9m, with a field of view 6 degrees x 4.5 degrees and a motorised focusing range from 3m to infinity.

The thermal imaging camera is shielded from the harsh conditions in the tapping 'front line' by a comprehensive enclosure incorporating a robust housing with a durable sapphire protection window, an adjustable mounting assembly for precise alignment with the tapping stream, and air purging and water cooling services.

Protection against the impact of liquid metal on the enclosure and sapphire window is provided by a sacrificial protection plate and sighting tube. All the services and signal connections are at the rear of the housing for added protection.

Top of pageTEMPERATURE MEASUREMENT PROBLEM-SOLVER BACK IN TOWN FOR IRON AND STEEL SHOW

TEMPERATURE MEASUREMENT PROBLEM-SOLVER BACK IN TOWN FOR IRON AND STEEL SHOW

When infrared temperature measurement specialist Land Instruments International exhibits at the iron and steel show AISTech 2005 (9th to12th May 2005 Charlotte, North Carolina), it will be the latest in an unbroken chain of attendances and the companys 58th year of continuous service to the steel industry.

Iron and steel is a key industry for us, which is why we have always exhibited at AISTech (formerly AISEs Iron & Steel Show ) regardless of the state of the market,
said Bud Foran, President in Land Instrument Internationals USA office based in Newtown PA.
In fact there have been instances in recent years when we have been the only infrared thermometer company present.

Land offers arguably the most comprehensive range of infrared thermometers for the many applications encountered in iron and steel manufacture.
Many were customised as a solution for a particular problem in the first instance, and have since been refined in the light of decades of experience.

Problems successfully addressed include: measuring molten metal temperatures in the furnace without using dip thermocouples; checking the condition of torpedo car refractories; minimising the carry-over of slag into the ladle during the tapping of liquid steel; compensating for background reflection when monitoring the temperature of reheat furnaces; and measuring steel strip temperatures during galvannealing.

Temperature control during hot rolling of steel slabs and billets has always been central to Lands work in the steel industry and the companys technology was recently customised for the production directly from the hot strip mill of dual-phase ferrite/martensite steel, which is now widely favoured by car manufacturers for passenger protection components such as side impact beams.

Top of pagePR500105 - TUBE FURNACE TEMPERATURE CHECKING MADE EASY

Tube furnace temperature checking made easy Land Instruments International has simplified the task of downloading and analysing the temperature measurements of reheat and reformer tube furnaces taken by its Cyclops 153 and FurnacePro portable infrared thermometer.

The new Cyclops DL-1000 Data Logging System combines Land's own software with a Pocket PC on which readings can be stored and then transferred to a partnership PC as a .txt file, for display and analysis using wordprocessing and spreadsheet programs.

A number of readings of the furnace background temperature are made until a satisfactory average measurement has been recorded. The user can then take readings of the tube temperature itself, each of which is adjusted for reflection errors by the Data Logging System's error correction program to yield the true temperature.

A choice of options is offered at the start of each measurement logging session, including thermometer type, temperature units and text identifier. A timed acquisition function can be set to record temperature data at pre-determined intervals from 1 to 3,600 seconds.

The Cyclops DL-1000 Data Logging System can be purchased as an add-on to Cyclops thermometers already in use, or specified when buying a new instrument. It is also available with or without Pocket PC.

Top of pagePR510105 - INFRARED CALIBRATION LABORATORY RAISES STANDARDS

Infrared calibration laboratory raises standards Non-contact temperature measurement equipment manufacturer Land Instruments International has consolidated the leading position of its calibration laboratory by setting new standards of accuracy in temperature calibration.

For blackbody sources in the range -10 to 200C, the laboratory can now achieve a best measurement uncertainty of +/-0.8C - a performance that is matched only by the National Physical Laboratory. The uncertainty figure for thermocouples, radiation thermometers and other blackbody sources is between +/-1 and 4C.

Land's calibration laboratory was the first to be accredited to issue United Kingdom Accreditation Service (UKAS) certificates for thermal measurements, and to meet the requirements of ISO17025.

Set up originally for the initial calibration of Land's own instruments, the laboratory is used by companies of all kinds whose processes depend on accurate infrared temperature measurement - and even Land's competitors on occasion.

As well as calibrating and accrediting instruments, it advises customers on the best method of achieving traceability for their equipment and can also provide a re-calibration reminder service - especially useful for subcontractors to defence and aerospace organisations.

Top of pagePR491204 - NEW TEMPERATURE DATA LOGGING SYSTEM FOR POCKET PC

Land Cyclops portable infrared thermometer and the Cyclops DL-1000 Data Logging System Land Instruments International has introduced a data logging system that allows users of its Cyclops portable infrared thermometers to download and analyse temperature measurements of production plant or products.

The Cyclops DL-1000 Data Logging System combines Land's own software with a Pocket PC on which readings can be stored and then transferred to a partnership PC as a .txt file, for display and analysis using word processing and spreadsheet programs.

Although some Cyclops portables have an on-board storage facility, until now analysis has been limited to determining the highest, lowest and average temperatures, and the data is lost when the instrument is switched off.

The Data Logging System - which is suitable for use with the Cyclops 100, Cyclops 300AF/300bAF, C153/153A and FurnacePro - offers a choice of options at the start of each measurement logging session, including thermometer type, temperature units and text identifier.

The system can be configured to run in a timed acquisition mode that records temperature data at pre-determined intervals from 1 to 3,600 seconds.

For the Cyclops 153/153A and FurnacePro, there is also a Background Compensation function that automatically compensates for measurement errors in situations where the temperature of the target is lower than its surroundings, such as reheat and reformer tube furnaces.

The Cyclops DL-1000 can be purchased as an add-on to Cyclops portables already in use or specified when buying a new instrument, with or without Pocket PC.


Top of pagePR481204 - NEW HIGH STABILITY TEMPERATURE CALIBRATION SOURCE

New high stability temperature calibration source - P1600B2

A new primary blackbody temperature calibration source from Land Instruments International has been developed for calibrating industrial infrared radiation thermometers that is smaller, lighter, more stable and more accurate over a wider temperature range than its predecessor - and sells at a lower price.

Recommended for temperatures from 500 to 1600C, the bench-mounted LANDCAL P1600B2 heats up to 1400C in 1.5 hours, with a stability of less than 0.5C over a 60 minute period.

The high emissivity 50mm x 300mm conical-ended blackbody cavity is heated by six equally spaced silicon carbide heating elements to ensure a uniform and stable temperature along its whole length.

The diameter of the sighting tube has been increased to 49mm, providing a larger target suitable for calibration of a range of temperature measuring instruments including thermal cameras and process imagers.

The source can either be used as a primary standard, where the temperature is measured against a certified Platinum thermocouple, supplied as an optional extra, or for greater accuracy calibration by the comparison method can be adopted.

RS232C serial communications is available as standard, which can be used to program the source temperature set points remotely.

For ease of handling, the weight of the LANDCAL P1600B2 has been reduced to just 60kg.

An optical bench assembly is also available to aid mounting and precise alignment of thermometers into the cavity as an optional extra.

Top of pagePR040846 - THERMAL IMAGER GIVES HIGH PERFORMANCE AT LOW COST

The working thermographer will find the ergonomically designed Cyclops TI 814 light, compact and easy to use. The user will benefit from simplified controls, simultaneous display of the thermal image in both the bright LCD display and color viewfinder, and the practical advantage of TI 814 being powered by a standard rechargeable camcorder battery capable of more than three hours continuous operation.

In addition to plant condition monitoring, the Cyclops TI 814 can be used to gather and analyse temperature data for structural integrity inspections, quality control, and research and development.

Industries that can benefit include steel and glass, petrochemical and plastics, electrical and electronics, power generation, transmission and distribution, energy management, construction and civil engineering.

Top of pagePR450504 - LOW-COST IR THERMOMETERS SHOW THERMOCOUPLES THE DOOR

Non-Contact Thermometers

Non-contact thermometers that can be permanently substituted for disposable thermocouples without undue cost and technical complexity have been introduced by Land Instruments International.

An extension to Lands MF3 on-line infrared radiation thermometer series of infrared thermometers, the new models have outputs that match the voltage/temperature correlations of Type J and Type K thermocouples so that they can be used without changing the calibration of downstream processing.

They are intended for industrial applications where thermocouples and their attendant disadvantages are still commonplace, including the manufacture of products as diverse as plastics, rubber, timber, paper, textiles, paint, lacquer, liquids and food.

Overall measurement range is 0 to 500C, with an accuracy of +/-1.5% at an ambient 23C, a response time of 300ms and repeatability of +/-1%.

With dimensions of only 18.6mm diameter x 118mm, the MF3 on-line infrared radiation thermometer range is compact in both size and price, offering a good all-round performance with fixed emissivity compensation and a 5:1 field of view suitable for targets with a typical diameter of 60mm at a 300mm sighting distance.

Each MF3 on-line infrared radiation thermometer thermometer is housed in a rugged stainless steel body and supplied complete with a 1m pre-wired cable for simple connection into existing systems without configuration or technical input from the manufacturer.

Dedicated mountings and accessories include a water-cooled jacket for environments up to 80C and situations where the sides of the thermometer are subject to significant radiated energy.

Top of pagePR441203 - NEW PROCESS IMAGER FOR THIN SHEET PLASTICS TEMPERATURES
Process Imager For Thin Sheet Plastics

Land Instruments International has developed a completely new high-speed infrared linescanner system to measure process temperatures during the thermoforming, blowing, moulding and drawing of thin sheet plastics.

The temperature of thin sheet plastics is difficult to measure because the material is highly transparent over much of the infrared spectrum, and the wavelength at which measurements can be made varies according to the type and the thickness of the plastic.

Land has developed a solution to these problems with the new Landscan Pro LSP71 system, which is the outcome of a detailed study of the temperature behaviour of many types of plastics during manufacture. It has been designed to take accurate and reliable readings at an appropriate wavelength for, amongst others, PVC, polycarbonate, polypropylene, polyethylene, PET, cellulose acetate and polystyrene.

The LSP71 linescanner head is extremely compact in both depth and 'footprint' so that it can be installed in the restricted spaces often encountered on plastic thermoforming lines, such as the narrow gap between heater and press.

A sapphire protection window provides added durability.

The scanner can generate temperature profiles in the measurement range 50 to 350C at scan rates up to 100Hz, and at a resolution many times greater than competing products. Scan angle is 80, with a 100:1 field of view (95% energy) and a focus range up to 3000mm/118in.

The output from the LSP71 linescanner head is transmitted to the new Landscan Control signal processor, which provides serial and Ethernet data outputs that can be interfaced to local process control systems, or to Land's own software - Landscan Configuration Professional or Landscan WCA.

Ease of use are key features of the Landscan LSP71 system - from the built-in sighting laser for easy installation of the scanner to the cooling and mounting plate from which it can be removed for maintenance without the need for subsequent realignment.

Process Imager For Minerals and Metals

Production engineers in minerals processing or metals cold rolling who need a temperature profile of their process should take a look at the new Landscan Pro LSP6 series process imager from Land Instruments International.

Offering a high specification at a low cost, the new low temperature LSP6 series infrared linescanning systems have been designed for a wide range of industries, including two quite specific applications: monitoring the shell temperature of rotating kilns manufacturing cement, dolomite and similar minerals; and providing temperature distribution profiles of metals being cold rolled at less than 300C.

Although they are significantly very different, both applications share the fact that they are focused on a moving target object. In the case of the kiln, the linescanner is able to depict and record the temperature of the whole circumference of the shell - continuously and in far greater detail than is possible with, for example, occasional spot checks using a handheld infrared thermometer.

Temperature Profile

Other applications in the metals and mineral processing industries include conveyor belt protection and torpedo car and ladle safety.

Central to the system are the LSP60, LSP61 infrared linescanning system and LSP62 scanner heads, which can generate high speed temperature profiles at up to 100Hz in the measurement range 20 to 600C with an accuracy of +/-3C. They have a wide scan angle of 80 and a field of view of 100:1 (95% energy) maintained at all target distances.

LSP60 is intended for measurement of low temperatures in the range 20 to 250C; LSP61 infrared linescanning system covers mid range temperatures 50 to 400C and LSP62 the higher range of 100 to 600C.

These compact scanner heads can be installed where space is limited, and have a sapphire protection window for added durability.

A built-in Class 2 laser to define the scan plane and sighting angle is supplied as part of the package, making the initial set up quick and simple.

A complete range of mounting assemblies, water cooling and air purging options are also available - and the scanner head can be de-mounted for maintenance and put back in position without the need for realignment.

Completing the system is the new 19in rack mounted Landscan Control signal processor, which generates serial and Ethernet temperature data outputs that can interface to local process control or the new Landscan Configuration Professional and Landscan WCA software.
