Diaphragm Seal System

Diaphragm for Pressure Transmitters

Differential Pressure Level Solutions

Diaphragm seals are used to prevent the process medium from entering directly into the pressure-sensing assembly of the differential, gauge, or absolute pressure transmitter.

The applications that are suitable for pressure transmitter diaphragm seal systems manufactured by Yokogawa are measuring the liquid level, density, flow, and pressure of:

  • high/low-temperature fluids
  • highly corrosive/high viscosity fluids
  • the fluids which may cause clogging of impulse piping in the low temperature
  • toxic fluids
  • the fluids containing suspended solids that are deposited in the impulse piping and may cause clogging.
