YOKOGAWA EJA-E Series EJA110E-JFS4J-912DB/D3 Standard Traditional-Mount Differential Pressure Transmitter
The EJA-E series of transmitters is Yokogawa's most recent evolution of the DPharp family of pressure transmitters. 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 EJA110E is our standard traditional-mount differential pressure transmitter in this series.
EJA110E features include:
0.055% Accuracy (0.04% Accuracy optional)
0.1% Stability per 10 years
90 ms Response Time
Exida and TUV SIL 2 / SIL3 Certified
MWP 2,300 psi (MWP 3,600 psi option)

*1: HART 5 or HART 7 is selectable. Specify upon ordering.
*2: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of
inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage
to plant facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm
and the fill fluid can contaminate the user’s process fluids.
Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium
hypochlorite, and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the
wetted parts material.
*3: Only applicable for Wetted parts material code S.
*4: Not applicable for measurement span code F.
*5: Not applicable for electrical connection code 0, 5, 7, 9 and A.
*6: Not applicable for electrical connection code 0, 5, 7 and 9.
*7: Material of a blind plug; aluminum alloy for code 5 and 9, and SUS304 for code 7.
*8: Not applicable for output signal code G.
*9: Not applicable for output signal code F.

What CSA approval codes are available for the EJA-E?
In addition to the /CF1 option, we now have the /CS1 and /CU1 options for CSA approval codes. /CS1 option includes the following: CSA Intrinsically safe ApprovalCertificate: 1606623 [For CSA C22.2]Intrinsically S.
What is the EJA-E series
EJA-E is Yokogawa's new transmitter series for enhancement of our Dpharp line-up. It follows the basic construction of the existing EJX series with improved specifications compared to the EJA-A series.
Why is the EJA_E different than EJX but looks the same ?
Although the basic construction of the EJA-E is similar to the EJX series, the actual manufacturing processes like sensorcharacterization, calibration / verification are different.
