- When specified process connection style code E, maximum range and span are 7 MPa (1000 psi.)
- Material of a blind plug; aluminum alloy for code 5 and 9, and SUS304 for code 7.
- 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 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 hightemperature steam (150??C [302??F] or above). Contact Yokogawa for detailed information of the wetted parts material. - Hastelloy C-276 or N10276.
- When specified flushing connection ring code A or B, exclusive gasket is provided for transmitter side.
- Wetted parts material code TW (Tantalum) cannot be applied.
- Not applicable for flashing connection ring code A and B.
- In case of wetted parts material code HW (Hastelloy C), TW (Tantalum), and UW (Titanuym) for 2-inch pressure 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.
- Estimated Lead Time: 8 - 12
