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.
