ORI - Model 0-5 to 0-300 PSID -Diaphragm Differential Pressure Gauges
These diaphragm 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.
Our 1516 Series models are our most popular diaphragm differential pressure gauge design. They combine a highly-sensitive sensor with high line pressure capabilities.
- 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
Our 1800 Series diaphragm differential pressure gauge models are our most sensitive sensor designs. While being sensitive they also handle high line pressures up to 150 psi!
Switches, Relays, Transmitters
A variety of reed switches and relays can accompany these diaphragm differential pressure gauges, or the sensor can be supplied on its 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 a voltage output.
- Rugged, weatherproof design
- Gauge, switch and transmitter versions
- Popular in filtration, flow and level measurements
