Diaphragm Seal Pressure Gauges

Odin, an IS0 9002 company, in collaboration with Ametek, USA, (Mansfield and Greens division) offers diaphragm seal pressure gauges. These diaphragm seals are protective devices designed to isolate pressure gauges, pneumatic transmitters and other instruments from potentially damaging process media. The diaphragm seal typically comprises of a metal. Teflon or elastomer diaphragm mounted between two flanges and sealed to prevent leakage of process gases or fluids. The space on the instrument side of the diaphragm, the connections and the instrument sensing element are all completely filled with instrument oil, silicon or other suitable fluid. When process line pressure is applied, the diaphragm exerts equal pressure on the instrument side of the seal producing a reading on the gauge or other instrument. The instrument may be attached directly to the diaphragm seal or connected remotely by means of a filled length of capillary tubing. Diaphragm seals can be used with pressure or vacuum instruments incorporating C-type, helical or spiral bourdon tubes, bellows, diaphragm, or electronic strain gauge sensing elements.
