EJA310E Traditional-mount Absolute Pressure Transmitter
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 EJA310E is our traditional-mount absolute pressure transmitter in the series.
EJA310E standard features include:
± 0.1% Accuracy
± 0.2% Stability for 10 years
90 ms Response Time
Exida and TUV SIL 2/3 Certified
3,600 psia Maximum Over Pressure (MWP)
Local Parameter Setting (LPS)
Available with HART 5/7, 1 to 5 VDC HART 7 (Low Power), FOUNDATION Fieldbus, PROFIBUS PA, or BRAIN communication.

FieldMate PC based communication platform allows management of your entire instrument inventory.
FieldMate HHC allows you to take that information into the field.
LPS can update 9 parameters in the field without the use of an HHC.
Simple Troubleshooting
Save time, Save money
Local intuitive display with simple error messaging.
NE107 compliant alarms in FieldMate make troubleshooting easy.
Less Inventory
Universal Mounting
Reduce stock by 50%.
Consolidate inventory of different flange configurations. Yokogawa transmitters are available with flanges using flexible vent and drain locations to met any installation need.
High Inventory = Stagnant Money
Safety as Standard
Reduce stock.
No need to stock separate inventory for safety and non-safety applications. With safety as a standard, Yokogawa transmitters can be used for either application.
For Yokogawa, safety is never an option.
No Learning Curve
