Differential Pressure Gauge Manufacturer Solutions

A Leading Manufacturer of Differential Pressure Gauges, Switches and Transmitters

  • Magnetic movement allows the simultaneous sensing of both pressures while isolating the DP gauge function from the pressure chamber without the use of mechanical seals
  • Can indicate small values of differential pressure

Differential Pressure Gauge, Switch & Transmitter Overview

During more than fifty years in business, Orange Research has earned a reputation as a world-leading differential pressure gauge manufacturer. Our gauges measure the difference in pressure between two points in a system and present the resultant differential pressure directly on a single gauge dial. A magnetic movement allows the simultaneous sensing of both pressures while completely isolating the differential pressure gauge function from the pressure chamber without the use of mechanical seals.

Unlike ordinary pressure gauges, differential pressure gauges can indicate small values of differential pressure even when used at high line pressures. In addition to our differential pressure gauge manufacturer solutions, Orange Research offers differential pressure switches supplied with reed switches or relays to initiate alarms, activate other equipment, or to shut a system down. Two switches are installed when high and low limit control is desired.

Orange Research has developed a series of differential pressure transmitters with the ability to transmit data signals.


The microprocessor-based instruments are equipped with unique Hall effect sensors that convert the differential pressure gauges’ normal magnetic movements into electric signals. After processing, the DP gauge units provide analog output for remote location monitoring. Since the usual pointer-and-dial gauges continue to operate, local station readout is always available. Users can select current or voltage outputs.

As an innovative and industry-leading flow measurement and differential pressure gauge manufacturer, Orange Research produces our differential pressure gauges, switches and transmitters to meet customer requirements. With parts designed and made in the U.S, and recognized for precision, accuracy and dependability, we serve customers in a variety of industries and applications.
