The EJA530E is an in-line mount gauge pressure transmitter and is part of the most recent evolution of the DPharp family, the EJA-E series. It features a single-crystal silicon resonant sensor and is suitable for measuring liquid, gas, or steam pressure. The_EJA530E outputs a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup, and monitoring via BRAIN or HART communications and self-diagnostics.

EJA-E series models in their standard configuration, with the exception of the Fieldbus, PROFIBUS, and Low Power types, are certified as complying with SIL 2 safety requirements.

  • Accuracy: ±0.055% of Span
  • Response Time: 90 msec
  • Stability: ±0.1% of URL per 10 years

Enhanced Product Quality: The EJA530E with DPharp digital sensor offers the performance needed to run your operations at peak performance. This ensures on-spec product, reduced waste, and improved yield, helping you increase profitability.

Digital Performance

Other pressure sensor technologies require an analog to digital conversion before the signal can be processed, introducing additional errors. In Yokogawa’s pressure transmitters, the DPharp sensor directly outputs a digital signal, eliminating the need for analog to digital conversion and improving performance.

Tighter Process Control

Poor performing pressure transmitters can lead to you having to run at a lower than desired set point in your control loop or scrap product that doesn’t meet spec. The DPharp sensor exhibits greater linearity and repeatability with no inherent hysteresis, providing tighter process control.

Reduced TCO: The EJA530E reduces total cost of ownership by having safety as standard, extending calibration intervals, and utilizing a common communication platform for all protocols.

Extended Calibration Check Intervals

Yokogawa EJA-E series pressure transmitters have the long-term stability of ±0.1% per 10 years under all operational conditions, reducing calibration frequencies. As you gain experience with these transmitters, the interval between calibration checks is extended. Long-term this can help reduce your maintenance cost by up to 34%. Spend your time where it is needed.

Increased Plant Availability: The proven DPharp technology of the EJA530E increases plant availability with its advanced diagnostics and quicker resolution of maintenance issues through multiple communication options. Verified by independent third parties around the world, our transmitter provides superior reliability and performance.
