Vibration Transducer connection
Vibration Transducer connection
(OP)
For some make of vibration transducers, the cable screen is connected to the instrument earth (0V) at the monitor end and not connected to anything at the transducer end to avoid earth loops if the machine earth is at a different potential, that is the positive and negative wires are insulated from ground and the screen is isolated within the transducer.
For some few,the screen is connected to the body of the transducer.
What are the pros and cons of each ?

It probably has a lot to do with which end has the quietest inherent earth.
