why are set -10vdc in bently neveda vibration system.
Answer Posted / mohd
when the shaft moves toward the probe ,the gap vpltage will
change and that will be reflect on the negative voltage .
the main idea of using -10Vdc is to avoid interfering with
the noise signal which could give error in the reading .

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
