SV is the set point, and PV is the measurement valueThe remote pressure gauge usually converts pressure into electrical signals. The electric contact pressure gauge changes when the pressure approaches the setting pressure, and the signal contacts are normally open and normally closed. The electric contact pressure meter provides the start stop signal for the control circuit of the frequency converter, and the remote pressure gauge adjusts the output of the frequency converter, that is to say, to control the amount of the upper water.
