Diaphragm Seals



Allow to insulate the measurement component of a pressure gauge, sensor or pressure switch from corrosive, pasty or coagulated fluid.

The pressure of the measured product is transmitted to the measurement instrument through a diaphragm (stainless steel, monel, inconel, hastelloy, tantalum, teflon) and a fluid (generally oil).

The measurement instrument and its diaphragm seal, vacuum filled in the workshop, form a complete assembly.

SOME PARTICULAR APPLICATIONS

  • Level measurement on tank bottom
  • Level measurement in pressurized enclosure
  • Hygienic pressure measurement
  • Fluid control at temperatures 50°C to +370°C.
  • Measurement of crystallized products

On request :

  • Special constructions in monel, hastelloy, tantalum, titanium, PTFE, PVDF, PVC ...
  • Panelling PTFE, diaphragm doubled PTFE.
