Optional Codes

¨/ 可選范圍

The “?” marks indicates the most typical selection for each specification. Example: EJX530A-DAS4N-012NN/¨.

*1: 哈氏合金 C-276 or ASTM N10276.

*2: Not applicable for combination of capsule code D and wetted parts material code H.

*3: Not applicable for 輸出信號 code F.

*4: 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.

*5: Not applicable for 電氣連接 code 0, 5, 7 or 9.

*6: Material of a blind plug is aluminum alloy or 304 SST.

*7: Not applicable for 電氣連接 code 0, 5, 7, 9 and A. Content rate of copper in the material is 0.03% or less and content rate of iron is 0.15% or less.

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.
