What are DP Gauges?

Mid-West Instrument DP gauges are designed to measure the difference in pressure between two points in a system and display the resulting DP measurement on the gauge dial. The magnetic movement allows the simultaneous sensing of both pressures while completely isolating the DP gauge function from the pressure chamber without the use of mechanical seals. Unlike ordinary pressure gauges, DP gauges will indicate small values of differential pressure even when used with high line working pressures.

Mid-West Instrument DP switches are supplied with reed switches or relays to initiate alarms, activate other equipment, or shut the system down. Two switch units are installed when high and low alarms required.

Mid-West Instrument has engineered a series of DP transmitters with the ability to transmit data signals. The microprocessor based instruments are equipped with proprietary magnetic sensors that convert the gauges’ normal magnetic movements into electric signals. After processing, the DP gauge units provide 4-20 mA output for remote location monitoring. Since the usual pointer-and-dial gauges continue to operate, local station readout is always available.
