Aluminium extrusion temperature
measurement
New range of products, system features and keen pricing are the benefits of the revised range of infrared thermometer systems for aluminium extrusion from Land Instruments International
The range provides accurate and reliable temperature measurement at all the critical stages of extrusion, beginning with the Aluminium Billet Thermometer (ABT), which temperature profiles the billet as it passes from the heater to the press and can accommodate considerable variation in alloy type and surface roughness The new Fibroptic Aluminium Die Thermometer (ADT) confirms that dies are at optimum temperature (typically 450 degrees C, or 840 degrees F) upon leaving the die oven

Three-year warranty on trouble-free thermal imager
Land Instruments International is so confident of the reliability of its new FTI-E fixed thermal imaging system that it is supplying it with a market-beating three-year warranty
Modular flue gas sampler goes almost anywhere
The new Land Instruments International Unicorn flue gas sampler is designed for continuous monitoring of emissions with moderate particulate content from gas turbines and similar combustion systems
The Aluminium Extrusion Thermometer (AET) is tailored to measurements at the die exit, automatically compensating for alloy type, section profile and partial sighting on the product.
Its extremely high long-term stability avoids the need for frequent, elaborate set-up procedures.
The same function at the quench exit is provided by the Aluminium Quench Thermometer (AQT).
AET and AQT thermometers can be used together with an input of ram or section speed to verify the cooling rates needed to realise the desired mechanical properties in temperature-critical alloys.
Both the AET and AQT thermometers have a built-in alignment laser as standard.
Uniquely, sighting is aligned down the optical axis to avoid the risk of misalignment from parallax errors and the orientation of the thermometer relative to the section.
Signal processing is performed by the new Landmark Graphic AE, which can accept inputs from up to four thermometers and provide digital and graphical displays of temperature data and quench rates across the entire extrusion process.
Completing the new range is an electronic actuator assembly for safe and rapid realignment of AET and AQT thermometers, which is especially useful when frequent die changeovers are required. Request a free brochure from Land Instruments International ...
