Infraredsensors with ATEX/IECEX Certification

Fluke Process Instruments now offers all models of its versatile MI3 Infrared Sensor series 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, a communication box, and an Ex power supply. All three components are IP65-rated, and each can be easily exchanged in the field without re-calibration 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 in total, providing high flexibility for setting up safe monitoring scenarios. The MI3 series comprises pyrometers for various spectral ranges and applications, including the 1M and 2M short wavelength models with an excellent 100:1 resolution and 10 ms response time, which are suitable for monitoring temperatures up to +1,800 °C. Each intrinsically safe MI3 sensing head is labelled with the Ex i certification. MI3 sensors have excellent EMC characteristics and can be used in ambient temperatures up to +180°C. Communication boxes are available with RS485, Modbus, Profibus, Ethernet, and Profinet IO interfaces and with four galvanically isolated analog outputs.
