Model and Suffix Codes
NOTE:
The marks indicate the most typical selection for each specification.
HART 5 or HART 7 is selectable. Specify upon ordering.
Not applicable for output signal code G.
Forged version of the material may be used.
See table 3 Gasket contact surface .
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.
When specified flushing connection ring code A or B, exclusive gasket is provided for transmitter side.
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), TW (Tantalum), and UW (Titanuym) for 2-inch pressure flange, specify capillary length from 1 to 5 m.
