Lower limit of ambient temperature: –15°C (5°F) The “•” marks indicate the most typical selection for each specification.The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175 (2003). Please refer to latest standards for details.HART 5 or HART 7 is selectable. Specify upon ordering.Cast version of 316 SST. Equivalent to SCS14A.Not applicable for electrical connections code 0, 5, 7 and 9.Not applicable for output signal code G.Forged version of the material may be used.See Table 3 ‘Gasket contact surface’ on Page 5.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.When specified flushing connection ring code A or B, exclusive gasket is provided for transmitter side.Indicates the process temperature limit of high pressure side. The process temperature limit for low pressure side is –40 to 120°C except fill fluid code -D.The distance ‘S’ is extended in 30mm.In case of wetted parts material code TW (Tantalum), the process temperature limit is –10 to 200°C.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.The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by option code D1, D3, and D4.Applicable for Low Pressure Side Process connection code 1, 2, 3, and 4.The unit on the certificate is always MPa regardless of selection of option code D1, D3, or D4.A flushing connection ring will not be applied when conducting the pressure test or leak test.Pure nitrogen gas is used for oil-prohibited use (option code K1, K2, K5, and K6.)
