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.
Type：
GE-373-EX wall mount type for room or outside area
GE-373-EX insert type for duct or pipe air flow
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。
