NOTE:
Not applicable for electrical connection code 0, 5, 7 and 9.
Not applicable for output signal code G.
Forged version of the material may be used.
See table 3 'Gasket contact surface' on page 6.
Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of inappropriate materials can result in 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 fill fluids 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).
When specific flushing connection ring code 1 or 2, exclusive gaskets are provided for transmitter side.
Even in case where fill fluid code D (fluorinated oil) is selected, if degrease cleansing treatment or both degrease cleansing and dehydrating treatment for the wetted parts is required, specify option code K1 or K5.
In case of wetted parts material code TW (Tantalum), the process temperature limit is -10 to 200?C.
In case of wetted parts material code HW (Hastelloy C) and TW (Tantalum) for 2-inch process flange, specify capillary length from 1 to 5 m.
The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by option code D1, D3 and D4.
