Diaphragm Seal System

[Diaphragm Seal System]
Diaphragm seals are used to prevent process medium from entering directly into the pressure-sensing assembly of the Differential, Gauge or Absolute pressure transmitter.

Application which is suitable for diaphragm seal system...
For 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 which are deposited in the impulse piping and may cause clogging.

Direct Mounted Diaphragm Seal System consists of differential pressure transmitter with single direct mount diaphragm seal.

Diaphragm Seal System consists of differential pressure or gauge pressure transmitter with one or two diaphragm seal.

Absolute Pressure Diaphragm Seal System consists of absolute pressure transmitter with single diaphragm seal.

 

Digital Remote Sensor (DRS) Transmitter connects two pressure sensors, master (high-pressure side) and slave (low-pressure side) in a remote location, with DRS dedicated communication cable to measure differential pressure.

Direct Mounted Diaphragm Seal System consists of gauge pressure transmitter with single direct mount diaphragm seal.

Application Note
Overview:

DP Level transmitter configuration can be very time consuming. Yokogawa DPharp EJA/EJX Pressure transmitters realize reduction in man hours by smart level setup feature.
