All models from the MI3 infrared sensor series now are available as intrinsically safe versions for use in hazardous environments. The intelligent miniature sensors are fully ATEX- and IECEx-certified for use in Zones 1 and 2 (gas) and Zones 21 and 22 (dust). The manufacturer supplies a complete intrinsically safe package, including the sensor, communication box and Ex power supply. All three components are IP65-rated, and each can be exchanged in the field without recalibration of the entire system. One or two intrinsically safe MI3 sensing heads can be powered by one power supply. The sensor cables can be up to 30 m long.
