Listing ID #4037984

Recommended where the fluid is highly corrosive, contaminated, viscose or liable to crystalize inside the measuring system. Diaphragm seals are the separation stage between medium and gauge. The gauge above the diaphragm s.eal is filled with suitable oil which transmit the pressure acting on the diaphragm to the bourdon tube. The diaphragm is welded to the upper part of sealed unit and therefore It is possible to open diaphragm sealed unit without removing the gauge to clean the diaphragm. The upper and the lower part are connected by two tension flanges. The standard material for diaphragm is AIS1316. However, diaphragm and all wetted parts can also be given with special material such as Tantallum, Hastelloy B2 or C4, Titanium and Monel 400. Pressure gauge can be in any of the Type 1, 3 and 5 and process connection with Standard BSP or NPT threads or flanged connection confirming to ANSI, BS or DIN Specifications. The gauge and Diaphragm Seal can be separated with capillary tube upto 5 meters in length, available in dial size 100 mm and 150 mm, Accuracy ± 1% in all standard range
