Diaphragm Pressure Gauge
Diaphragm Pressure Gauge is designed to isolate the sensing element of pressure gauges from process fluids that they may be corrosive, viscous, sedimentous and / or with a high temperature. They are mainly composed of all-stainless pressure gauge and diaphragm seal.
Specifications
Dial sizes: 4″, 6″ (100 & 150 mm)
Case: 304 Stainless Steel case.
Wetted parts: 316 Stainless Steel
Lens: Polycarbonate or Safety Glass
Pressure Range: 0 to 1,000 psi/Bar

Protection
– If pressure gauges are to be used for steam service, a siphon tube filled with water must be installed between gauge and line to prevent live steam from entering the Bourdon tube.
– A gauge cock should be installed in the pressure line. This might be the standard shut-off valve or a needle valve for throttling pressure pulses.
– If severe pulsation exists, the gauge should be protected by adding a throttling orifice
screw in the gauge socket or by addition of a pulsation damper, such as a snubber.
– A diaphragm seal should be used in applications where process media should not come in contact with gauge.
