Hi all,
Here on a drilling rig we use some pressure sensor which is 4-20mA and Intrinsically Safe (IS). Everything is grounded properly... However, one day we observed that some sparks were generated when the sensor cable touch a metal part of another equipment. We are wondering from where could this spark generated?
Any ideas would be appreciated.
Thank,
