Diaphragm Sealed Pressure Transmitter

Yokogawa EJX118A Diaphragm Sealed Pressure Transmitter

The EJX-A series is Yokogawa’s premium performance line of DPharp transmitters. Released in 2004, it offers the performance and stability needed in demanding applications. The EJX-A series performance makes it the thoroughbred of the DPharp family of pressure transmitters.

The EJX118A is the Differential Pressure Transmitter with Remote Diaphragm Seals in the series.

EJX118A features include:

  • 0.15% Accuracy
  • 200 ms Response Time
  • TUV SIL 2 / SIL 3 (IEC 61508) Certified
  • Local Parameter Setting (LPS)
  • 10-segment Signal Charaterizer
  • Active Capillary Fill Fluid Density Compensation

Diaphragm Sealed Pressure Transmitter

Yokogawa EJX118A Diaphragm Sealed Differential Pressure Transmitter

Diaphragm seals use to prevent process medium form entering directly into the pressure-sensing assembly of the differential pressure transmitter, they connected to the transmitter using capillaries filled with fill fluid.

EJX118A Diaphragm Sealed Differential Pressure Transmitters can use to measure liquid, gas, or steam flow, as well as liquid level, density, and pressure. EJX118A outputs a 4 to 20 mA DC signal corresponding to the measured differential pressure.

Its highly accurate and stable sensor can also measure the static pressure which can show on the integral indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response, remote set-up using communications, and diagnostics and optional status output for pressure high/low alarm. The multi-sensing technology provides the advanced diagnostic function to detect such abnormality as an impulse line blockage.

FOUNDATION Fieldbus and PROFIBUS PA protocol types are also available. All EJX series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified by TÜV as complying with SIL 2 for safety requirement.
