EJA430E Traditional-mount Gauge Pressure Transmitter

Gauge Pressure Transmitter

The EJA430E is a high-performance gauge pressure transmitter used to measure liquid, gas, or steam pressure. Featuring Yokogawa DPharp sensor technology, the EJA430E delivers measurements accurately, quickly, and reliably.

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.

Key Features

Digital Performance

  • 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

  • The DPharp sensor exhibits greater linearity and repeatability with no inherent hysteresis, providing tighter process control.

Safety as Standard

  • At Yokogawa, safety is never an option. All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3 by Exida® and TÜV Rheinland®.

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.

Diagnostics

  • Unlike traditional analog sensors, which are passive, the DPharp sensor is an active digital sensor. This means it is inherently safe and constantly supplying a signal even if there has been no change in process pressure. If the signal is lost, the transmitter’s self-diagnostics will alert you if there is an issue.

Your team went above and beyond

I just wanted to let you know your team went above and beyond. I requested a replacement valve that needed to meet our new requirements. Dave and James produced a valve that met all my needs. Without the need for a pipe modification. Which will help us with keeping the down time of the equipment low. There was an issue that caused this valve to be needed by Wednesday. These two individuals jumped through hoops to make sure I will have the valve by Wednesday. They also have a backup valve option just in case. The hard work and reassurance helped me convey to my management that your team is crucial to our success. I appreciate everyone that helped.

Easy and affordable

I Would like to comment on how easy it was to install the new Schubert & Salzer valves that replaced the bigger and heavier globe valves. The spool pieces provided by Shubert made this transition very easy and affordable.

No calibration needed

Eight years later...no calibration needed! Yokogawa active digital pressure transmitters installed throughout the facility are still in service and have never needed any zero or span adjustment.
