EJA438E Gauge Pressure Transmitter with Remote Diaphragm Seal

 Gauge Pressure Transmitter with Remote Diaphragm Seal

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-A series with the performance of the thoroughbred EJX-A series to deliver the type of product you have come to expect from Yokogawa.

The EJA438E is a gauge pressure transmitter with a remote diaphragm seal in the series.

Key Features

Digital Performance

  • Yokogawa's DPharp digital sensor offers twice the performance and stability of the competitor's analog sensors.

Superior Design

  • All remote seal systems on the market use fill fluid to 'transmit' the process pressure from the remote diaphragm seal to the pressure sensor in the transmitter.

Rugged Construction

  • Ruggedly constructed differential pressure transmitter can help your plant reduce failures. Yokogawa's DP transmitters have construction features that are designed to allow it to outlive your plant. 

Multiple Communication Options

  • Yokogawa offers several platforms to communicate to your transmitter.

    FieldMate is a PC based communication platform that can communicate with your transmitter and manage your entire instrument inventory.

    FieldMate HHC is a traditional hand-held platform that allows you to take that information into the field.

    Forgot your HHC? No problem. The LPS feature on the transmitter allows you to update 9 parameters without the use of an HHC.

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.

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.
