All models of the Raytek MI3 Compact Series infrared sensors are now also available as intrinsically safe versions for use in hazardous environments. Intrinsically safe devices prevent explosions in hazardous locations by limiting the energy and surface temperature of the device under normal operation, or when conditions arise that could become hazardous. Devices are approved as intrinsically safe only after passing the 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 and one or two intrinsically safe MI3 sensing heads can be powered by one power supply. The sensor cables can be up to 30m (98ft) long in total, providing flexibility for setting up safe monitoring scenarios. The communication box, power supply and sensing heads can each be exchanged in the field without re-calibration of the entire system.
