Temp.: –30 to 60°C (–22 to 140°F)Ui=30 V, Ci=27.6 nF, Li=0 µH(8) Calibration unit(9) /D3 bar calibration (bar unit) 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.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ASTM N10276.Not applicable for combination of capsule code D and wetted parts material code H. Threads are based on the withdrawn DIN 16 288.Material of a blind plug; aluminum alloy for code 5 and 9, and SUS304 for code 7.Not applicable for output signal code F.Applicable for Electrical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.The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by option codes D1, D3, and D4.
