The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family. Released in 2012, it combines the ruggedness and success of the work-horse EJA-E series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.
The EJA130E is a differential pressure transmitter designed to work in a high static pressure enviroment.
EJA130E features include:
Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION FieldBus, PROFIBUS PA, or BRAIN communication.

Digital DPharp sensor provides stable measurement in all operation conditions.
To some degree, all pressure sensors on the market provide stable measurement with variations in temperature and static pressure. But what happens when the sensor is over-pressured (pressure > sensor Upper Range Limit (URL)) - like occurs when a manifold is incorrectly sequenced during start-up or shutdown? Or a process upset? Analog sensors are actually damaged during these events requiring the transmitter to be recalibrated to return to accurate operation or even replaced. Yokogawa's transmitters can withstand large overpressure events. (*See the table below.) Once it returns to normal operating pressure (pressure < URL of the sensor), the transmitter will return to operation within the defined accuracy and stability specifications - no need to recalibrate. Basically, the Yokogawa DPharp sensor has a larger operational envelope compared to an analog sensor.

The Yokogawa pressure transmitter series' performance and reliability has been verified by independent third parties from around the world.
All Yokogawa pressure transmitters are designed and certified to IEC61508:2010 Parts 1 through 7 and IEC61511:2004 Parts 1 through 3. They are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications with no special option required. With Yokogawa's transmitters, no longer will you have to maintain two seperate inventories - one for production applications and one for safety applications.
Functional Safety = Reliability
