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 flashing connection ring code A and B.Material of a blind plug is aluminum alloy or 304 SST.Not applicable for output signal code F.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 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.
