Differential Pressure Transmitter

Yokogawa EJX130A Differential 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 EJX130A is the traditional-mount high-static Differential Pressure Transmitter in the series.

EJX130A features include:

  • 0.04% Accuracy
  • 0.1% Stability per 10 years
  • 4,500 psi MWP
  • 150 ms Response Time
  • Local Parameter Setting (LPS)
  • TUV SIL 2/3 (IEC 61508) Certified

Differential Pressure Transmitter

Yokogawa EJX130A Differential Pressure Transmitter

The high performance pressure transmitter EJX130A features single crystal silicon resonant sensor and is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. EJX130A 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 be shown on the integral indicator or remotely monitored via BRAIN or HART communications. Other key features include quick response, remote set-up using communications, diagnostics and optional status output for pressure high/low alarm. The multi-sensing technology provides the advanced diagnostic function to detect such abnormalities as an impulse line blockage or heat
trace breakage. 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.
