Raytek Non-contact temperature measurement of up to 3,000°C
Germany – Infrared temperature measurement companies Raytek and Ircon provide solutions for all scenarios involving digital or analog signals and automation environments featuring a variety of different fieldbuses or Industrial Ethernet protocols.
At this year’s Metec-Thermprocess exhibition, these two companies presented their comprehensive pyrometer program for the metalworking industry.
Among the highlights was the latest addition to the product family, the Raynger 3i Plus handheld infrared thermometer, designed for highly demanding hot environments, measuring temperatures of up to 3,000°C. A high optical resolution allows for accurate temperature readings from longer distances, the companies say. A heat-resistant “Red Nose” warning detector ensures operator safety and efficiency. Dual laser and scope sighting, visible even against red-hot backgrounds, are said to make this thermometer suitable for primary and secondary metals’ processes.
Also on show were a range of spot pyrometers for fixed installation, including one and two-color (ratio) pyrometers, and fiber-optic models suitable for extreme industrial environments. According to Raytec and Icon, installation in remote or hard to reach places is easy as the accompanying software allows for PC-based sensor configuration. Integrated automatic self-diagnosis functions ensure consistent accuracy. Through-the-lens, laser, and/or video sighting facilitate orientation. Motorised focus control enables remote sensor re-focusing. Cooling accessories open up applications in temperatures of up to +315 °C.
The Raytek MI3 line includes what is claimed to be the world’s smallest stand-alone pyrometer, at 28 mm x 14 mm. According to the company, two shortwave models accurately measure reflective surfaces and are therefore better suited for metal sheet processing than longwave infrared sensors. Also, MI3 sensors can withstand ambient temperatures of up to +180 °C without cooling and are available with Atex and IECEx certificates too, for use in potentially hazardous areas.
