*NEMA 4X switch models have a 1/2 inch NPT conduit port as standard. A DIN 43650A-PG11 with mating connector is optional, rated IP65 & NEMA 4X. More on our piston DP gauge electrical details.
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, hydraulics and heat exchangers, they are a low cost alternative to bourdon tube and bellows designs.
- Pressure body and wetted parts: aluminum,
brass & stainless steel - Dial sizes: 2.5″, 3.5″, 4.5″ & 6″
- Porting locations: In-line, back & bottom
- Mounting: Panel, wall & pipe
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.
Differential Pressure Gauges, 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 are also available. DPDT relays are offered for high inductance applications, such as those incorporating motors or solenoids. Transmitters offer a current or voltage output.
