REOTEMP Diaphragm Seals (or Chemical Seals) use a flexible barrier, or diaphragm, to isolate a pressure sensor (gauge, switch, transmitter, or transducer) from adverse effects of the process fluid.

Diaphragm seals are useful to:
  • Protect the sensor from the process media (corrosive, abrasive, viscous, or crystallizing media)
  • Protect the process from the sensor (sanitary process requiring clean-out, or high purity media)
A diaphragm seal, when properly mounted to its sensor and filled, will accurately transmit process pressure to the instrument. 

Pressure exerted on the flexible diaphragm is transmitted hydraulically to the instrument through the fill fluid, which fills the void between the diaphragm and the instrument, (including the bourdon tube, in the case of a pressure gauge).
