Description

Solid Front Pressure Gauge has a safety barriers inside it, that is  used to release the inner pressure caused by break of the elastic element when over loaded. Thus security of personnel establishment is ensured. Solid front pressure gauge has solid front, and it can be filled with liquid. It is available in the harsh and corrosive conditions. It’s particular safe with gaseous media.

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.
