　　The ‘☆’ marks indicate the most typical selection for each specification. Example: EJA530A-DAS4N-02NN/

　　The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use ofSUS316 material,there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.

　　1、Not applicable for Output signal code F and G.

　　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 personneland/or damage to plant facilities. It is also possible that the diaphragm itself can be damaged and that material fromthe 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 detailedinformation of the wetted parts material.
