Overview
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 EJA430E is a traditional-mount gauge pressure transmitter in the series.

The “*” marks indicate the most typical selection for each specification.
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175/ISO 15156. Please refer to the latest standards for details. Selected materials also conform to NACE MR0103.
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.
