The “*” marks indicate the most typical selection for each specification.
HART 5 or HART 7 is selectable. Specify upon ordering
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.
Indicated material is equivalent to ASTM M35-2.
Not applicable for electrical connection code 0, 5, 7 and 9.
Not applicable for output signal code G.
Applicable for Electrical connection code 2, 4, 7, 9, C and D.
Not applicable for output signal code Q.
Lower limit of ambient temperature is –15°C (5°F) when option code HE is specified.
Material traceability certification, per EN 10204 3.1B.
Applicable for process connections codes 0 and 5.
The unit on the certificate is always Pa unit regardless of selection of option code D1, D3 or D4.
