NOTE:
The '*' marks indicate the most typical selection for each specification.
The '#' marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of SUS316 material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
- 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. Contact Yokogawa for detailed information of the wetted parts material.
- Indicates material of cover flanges and process connectors.
- Diaphragm material is Hastelloy C-276 or ASTM N10276. Other capsule wetted parts materials are SUSF316L, SUS316L or ASTM grade 316L.
- SUS316 or ASTM grade 316.
- For Capsule code L when combined with Wetted parts material code H, M, T, A, D, and B, the maximum working pressure is 3.5 MPa {35 kgf/cm2}.
- If necessary, specify Mounting bracket code C, D or K.
The EJA-A series is Yokogawa's most successful pressure transmitter line. First released in 1991, it continues to offer high
performance and high reliability for any application. With an installed base of over 4-1/2 million EJA-A transmitters worldwide, it
