Product Description

GE-325-Ex Thermal Flow switch could be used to measure and monitor the Gas Flow and Liquid Flow, as a stability and sensitive Calorimetric flow switch, widely used in Petroleum Chemical Industry. It 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 SPDT PNP or NPN. 

 

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。
