bside the sensor is Ex approved but its GND on its body makes me suspicious. Usually, if an EX sensor has a metallic housing, this is to be connected to earth. Inside electronics then is not connected to the metallic housing usually. Just the opposite: A test voltage of about 500V is applied between 0V of sensor circuit and metallic housing of sensor and the resulting leakage current must not exceed a certain limit. said:
I am searching but not getting good results if Ex is require for such oils or not.... If there's no chance for any fire or explosion then there's no EX requirements. Kai Klaas |
