Differential Pressure Indicators

We have two product ranges for you. The Orange Research gauges have magnetic movements, and are meant to operate under rising pressure, eg filter applications. Significant hysteresis impairs accuracy on falling pressures, but the design is capable of very high overloads and static pressures, at very reasonable cost.

Piston designs are used on liquids only, on applications where some liquid migration from high to low is acceptable.

1201 35-700 kPad @ 20 MPa liquid with some liquid migration
1301 1 000 – 7 000 kPad @ 35 MPa liquid with some liquid migration

Diaphragm designs are used on other applications
1502 35 – 700 kPad @ 20 MPa
1516 7 to 35 kPad @ 10 MPa
1831 1,5 to 50 kPa @ 1 MPa

More conventional designs are available from Stewart Buchanan.
4503 30 kPad – 10 MPad at static 3-6 times dp
4901 10 to 200 kPad @ 2 500 kPa static
4906 10 to 2 000 kPad @ 22 MPa static (DP Cell)
