Ex-proof certified temperature sensors monitor hazardous areas
Devices are approved as intrinsically safe only after passing the rigorous approval process required by a recognized entity.
The MI3 miniature sensors are now fully ATEX and IECEx certified for use in Zones 1 and 2 (gas) and Zones 21 and 22 (dust). Raytek supplies a complete intrinsically safe package, including the sensor, communication box and an Ex power supply. All three components are IP65 rated. One or two intrinsically safe MI3 sensing heads can be powered by one power supply. The sensor cables can be up to 30m long in total, providing high flexibility for setting up safe monitoring scenarios. The communication box, power supply, and sensing heads can each be easily exchanged in the field without re-calibration of the entire system.
The MI3 is a rugged, IP65 stainless steel miniature pyrometer with integrated electronics. It is the smallest, fully functional, standalone digital infrared temperature sensor for fixed installations on the market today. The MI3 series comprises pyrometers for various spectral ranges and applications, including the 1M and 2M shortwave models with an excellent 100:1 resolution and 10 ms response time, which are suitable for monitoring temperatures up to 1800°C.
