ATEX Humidity Temperature Transmitter

GE-373-Ex Explosion Proof Temperature Humidity Sensor adopts a stabilized Ex-proof shell to isolate the flammable point from external gas and dust, achieve the Ex grade to Ex db IIC T6 Gb (-20℃≤Ta+80℃), Ex tb IIIC T85℃ Db (-20℃≤Ta+80℃). It has domestic and international ATEX explosion-proof certificates. There are a variety of range options, and the signal output can be 4-20mA or RS-485. At the same time, it meets the requirements of gas explosion-proof and dust explosion-proof. These transmitters can be used for indoor air temperature and humidity monitoring in various industrial plant, clean room, lab, machine room, office and airport, station, library and stadium, etc.

The objection of the declaration is in conformity with the relevant EU harmonization legislation: ATEX directive 2014/34/EU, Machinery directive 2006/42/EC. The ATEX grade is Ex db IIC T6 Gb (-20℃≤Ta+80℃), Ex tb IIIC T85℃ Db (-20℃≤Ta+80℃) IP65; or Ex II  3GD Ex dc IIC T6 Gc (-20℃≤Ta≤+80℃) and Ex tc IIIC T85℃ Dc (-20℃≤Ta≤+80℃)  IP65 for gas and dust explosion prevention。
