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.
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.
Not applicable for electrical connection code 0, 5, 7 or 9.
Hastelloy C-276 or ASTM N10276.
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 /HE is specified.
Applicable for output signal codes D and J. The hardware error indicates faulty amplifier or capsule.
The 1 to 5 V voltage output corresponding to 4 to 20 mA current output is applied to output signal code Q which is noncompliant to NAMUR NE43.
Material traceability certification, per EN 10204 3.1 B.
The unit on the certificate is always kPa/MPa regardless of selection of option code D1, D3 and D4.
Applicable for capsule code C.
Pure nitrogen gas or pure water is used for oil-prohibited use (option codes K1 and K2).
