Optional Codes

¨/ 可選范圍

The “?” marks indicate the most typical selection for each specification.

*1: Not applicable for 輸出信號(hào) code F.

*2: Users must consider the characteristics of selected 部件材料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.
