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. Hastelloy C-276 or ASTM N10276.Not applicable for output signal code G.Applicable for Electrical connection code 2, 4, 7, 9, C and D.Not applicable for option code /AL.Lower limit of temperature is –15°C (5°F) when /HE is specified.Applicable for output signal codes D, E and J. The hardware error indicates faulty amplifier or capsule.316 or 316L SST. The specification is included in amplifier code 2. 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.
