7. Operating Principle
The Diaphragm Seal functions by transferring applied pressure from the process medium to the pressure measuring instrument through a sealed internal fluid.
Step-by-Step Function:
-
Process pressure presses against the flush diaphragm.
-
The diaphragm deflects proportional to the applied pressure.
-
The displacement is transmitted through the fill fluid inside the seal.
-
The internal movement mechanism of the gauge or transmitter converts this into a pressure reading.
Because the process medium never contacts the instrument, contamination risk is eliminated, and clogging is prevented.
8. Compatibility and Installation
This diaphragm seal can be directly assembled to:
-
Pressure Gauges
-
Pressure Switches
-
Pressure Transmitters
-
Differential Pressure Instruments
Process Connections
Its compatibility with ISS / IDF, SMS, APV/RJT, and DIN 11851 ensures easy installation in existing sanitary piping systems.
Instrument Connections
Standard ½” BSP (F) or ½” NPT (F) allows integration with most industrial pressure devices.
9. Advantages of Using MT-S100SN
Using the Diaphragm Seal with Sterile Connection MT-S100SN provides measurable operational benefits:
-
