Sealed Diaphragm Pressure Gauge




INDUS make Diaphragm Sealed pressure gauges, also known as Chemical Seal Gauge are recommended where the fluid is highly corrosive, contaminated, viscous or liable to crystallize inside the system. Diaphragm seals is use to isolate the measuring system of the gauge from the corrosive Liquid. The gauge above the diaphragm seal is filled with Silicon Oil, which transmit the pressure acting on diaphragm to the bourdon tube. The gauge and diaphragm seal can also be separated with capillary tube up to 5Mtr in length.

Features :

  • Case with or without Glycerin filling.
  • Can be fitted with electrical Contact for Alarms & Signals for various process applications.
  • For Use upto Full Scale Value.
  • Available in measuring Units like Kg/Sqcm, PSI, BAR, MPa, Kpa & Dual Scale.
  • PTFE Coating (optional) for use in corrosive materials.

 

Applications
It is mainly used as a protection device to prevent corrosion, clogging or freezing of Bourden tube element from material such Urea, Tar, Crude, Slurry etc. in Chemical Plant & Machineries, Refineries, Power Plants, Steel & Fertilizer Plants etc.
