Explosion proof Thermocouple and resistance temperature detector_R940 series (ETR series)

R940 series (ETR series)

Service intended

Measuring the temperature in the area where combustible gas, particles and flammable liquid exist can be a very dangerous task. The electrical energy of measuring instrument is lower than electric motor, however, the malfunction of the instrument or the accident can cause to start the explosion. Therefore, ETR series is explosion proof type product which is designed to be used in a critical danger Zone 1 by acquiring IECEx and ATEX certification.
