Gauge (w/switch option): 1201PGS - 1A - 2.5B - A 0-15 psid, 2 switch to close at 10 psid ascending
Switch only (no gauge): 1201PS - 1A - 0-15 psid switch to close at 10 psid ascending
Piston Sensor Differential Pressure Gauges
These piston sensor differential pressure 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, brass or PVC. 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: Our piston sensor models are best for liquid applications as they have a slight amount of fluid migration from the high to low pressure ports. Select our diaphragm models for air or gas applications or where fluid migration cannot be tolerated.
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 current or voltage output.
