Orange Research Differential Pressure Gauges / Switches / Transmitters
Piston Sensors for Liquids: High-Pressure
A spring-loaded piston/magnet sensor is magnetically coupled to a pointer to indicate a pressure difference. Sensing is completely separated from the indicator, switches, relay or transmitter. A high pressure rated housing is machined from a single block making these a natural for high pressure applications. Includes the 1201, 1203 & 1303 series.
Diaphragm Sensor for Gases & Liquids
For air or gas applications and no bypass, consider the diaphragm sensor design. Built on a design similar to the piston units, a diaphragm replaces the piston and separates the high and low pressure ports. A variety of diaphragm designs are available; small for more common DP measurements, large for more sensitive applications and a rolling diaphragm for high DP measurements. The gauges can be accompanied by a switch, relay or transmitter. Includes the 1502, 1516, 1518 & 1831 series.
Hazardous Location Models
Switches, relays and transmitters are enclosed in UL, CSA, FM and CENELEC approved enclosures that have a gauge option for local indication. Choose one or two switches, SPST, SPDT or a DPDT relay, available in a variety of voltages. Transmitters allow for continuous remote location monitoring. These enclosures meet Class I, Div. I specifications along with Nema-3, 4X, 7, 9 and 12. Both piston and diaphragm sensor models are available to make this the most comprehensive offering in the industry. Includes the 1204, 1504 & 1514 series.
