Diaphragm Seal

Diaphragm Flange 316LSS can use for pressure gauge, pressure transmitter, level transmitter.

Diaphragm seal Flange  316LSS

Diaphragm seals are used for the protection of pressure measuring instruments in applications with difficult media. In diaphragm seal systems, the diaphragm of the diaphragm seal effects the separation of the instrument and the medium.

The pressure is transmitted to the measuring instrument via the system fill fluid which is inside the diaphragm seal system.

For the implementation of demanding customer applications, there are a wide variety of designs, materials and system fill fluids available. Aggressive, highly viscous, crystallising or hot media

■Process industry

■Machine building and automation

Flange with flush welded diaphragm

■ Common standards and nominal widths available

■Wide variety of different materials and material combinations


For use with pressure gauge , pressure transmitter , pressure switch , pressure transducers on process applications

  1. Process element materials capable of withstanding corrosive effects of certain fluids are not available
  2. The process fluid being measured would normally clog the pressure measuring device
  3. The process fluid in the measuring element might freeze due to changes in ambient temperature
