April 4, 2012 - Raytek introduces MMG7 pyrometer for use in the production of thin glass. The MMG7 sensor measures infrared radiation at a wavelength of 7.9 μm, tailored to the measurement spectrum to the reflecting medium and to the 300 to 900 °C measured temperature range. At shorter wavelengths, background radiation could distort the results, while surface reflection is too strong in the longer-wave area.
The point sensor has a 100:1 resolution, and achieves a precision of ± 1 % and a repeatability of ± 0.5 % or ± 0.5 °C. With a response time of just 120 ms, the device delivers reliable data even in very fast processes. The measuring devices feature simultaneous analog and digital outputs.
They can be integrated into automation networks via an RS485 interface. The devices are equipped with a through-the-lens sight and optionally with video or laser sighting. Accessories for the IP65 instruments include an air-purge unit or a ThermoJacket protective casing with integrated air-purge unit and cooling for use in ambient temperatures of up to 315 °C.
