The “•” marks indicates the most typical selection for each specification.
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175/ISO 15156. Please refer to the latest standards for details. Selected materials also conform to NACE MR0103.
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.
Hastelloy C-276 or ASTM N10276.
Not applicable for electrical connection code 0, 5, 7 or 9.
Not applicable for output signal code F.
