..., If you see EX designs / application notes the floating voltages(+ve or-ve) in Hazardous Area at sensor poin are tied to PE through suitable resistor (not strictly prohibitive). But EX means more than only this potential equalisation. There's is also this issue of inherently safe power supply of sensor. You cannot just simply add a cap and a resistor and by this make a non EX sensor an EX sensor. Unfortunately there's much more to fullfill and to comply with. Kai Klaas My sensor is Exia IIC T6 rated. Just using it. -Ap |
