*1: See Table 3 ‘Gasket contact surface’ on Page 4.

*2: When specified flushing connection ring code A or B, exclusive gasket is provided for transmitter side.

*3: Indicates the process temperature limit of high pressure side.

The process temperature limit for low pressure side is –40 to 120°C.

*4: The distance ‘S’ is extended in 30mm.

*5: In case of 部件材料code TW (钽), the process temperature limit is –10 to 200°C.

*6: Not applicable for gasket contact surface code 1.

*7: 哈氏合金 C-276 or ASTM N10276

*8: Not applicable for flashing connection ring code A and B.

*9: 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.

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.

*10: Forged version of the material may be used.

*11: Specify always with option code /K2 or /K6.
