Chemical/Diaphragm Seal Unit

General Instruments Chemical Diaphragm Seal Unit

GIC 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.
