Chemical/Diaphragm Seal Unit

Thermal Instrument is the leading Chemical Diaphragm Seal Unit manufacturer in India providing reliable solutions for accurate pressure measurement to the process industry worldwide.

Model:

  1. CSU

Chemical Diaphragm Seal Unit:

  • A diaphragm seal is a device in which a flexible membrane (diaphragm) seals and isolates the measuring instrument from the process medium.
  • The instrument side of the diaphragm is filled with appropriate fluid.
  • The pressure exerted by the process fluid on the Diaphragm is hydraulically transmitted through the seal fluid to the pressure-sensing element.

TESTS

  • Visual Inspection
  • Dimensional Verification
  • Accuracy Test
  • Hysteresis Test
  • Leak Test
  • Influence Of Mounting Position
  • Degree of Protection
  • Effect of Mechanical Vibration
  • Effect of Mechanical Shock
  • Endurance Test With Steady Pressure
  • Endurance Test With Over Pressure
  • Endurance Test with Cyclic Pressure
  • Safety Blow-out Test
  • Thermal Stability Test at Rated Temperature

Features:

  • The diaphragm seal protects the pressure sensor from the harmful and hazardous effects of the process fluid.
  • Optional features are a Capillary for Remote mounting of the Pressure Instrument, a Flushing Ring (Spacer Ring) for purging/cleaning the area below the diaphragm without removing the Seal from the process line, a Stud / Nut and gasket for assembling the Diaphragm Seal with the Process Flange.
