Diaphragm Sensor DP Gauges

These diaphragm sensor DP gauges measure the pressure difference between two points. Acting in the place of two pressure gauges, these units allow for one simple reading on an easy-to-read scale. Popular in filtration, flow and level applications, they are a low cost alternative to bourdon tube and bellows designs.

We offer them with bodies (and wetted parts) of aluminum, stainless steel or brass. A variety of dial sizes are also available, from 2.5 inch to 6 inch, with many porting and mounting configurations. Choose from a wide selection of standard options; enough to satisfy any requirement.

Note: Select these diaphragm models for air or gas applications or where fluid migration from the high to low pressure ports cannot be tolerated. Avoid applying reverse pressure when attaching to systems. This can damage the diaphragm sensor.

Switches, Relays, Transmitters

A variety of reed switches, relays and transmitters can accompany the gauges or be supplied on their own, without a dial. SPST switches are offered normally open (N.O.) or normally closed (N.C.). SPDT reed switches also are available. DPDT relays are offered for high inductance applications, such as those incorporating motors or solenoids. Transmitters offer a wide variety of outputs, such as voltage, current, frequency or RS 232. Click here for more information on switches, relays and transmitters.
