Calibration units(10) /D3 bar calibration (bar unit) Pressure test/ Leak test certificate(11) /T12 Test Pressure: 16 MPa(2300 psi)Nitrogen(N2) Gas(12)Retention time: one minute The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR0175/ISO15156. 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.Cast version of 316 SST. Equivalent to SCS14A.Material of a blind plug is aluminum alloy or 304 SST.Not applicable for output signal code G.Not applicable for output signal code F.Not applicable for amplifier housing code 2 and 3.Not applicable with color change option.Applicable for output signal codes D and J. The hardware error indicates faulty amplifier or capsule.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.The unit on the certificate is always Pa unit regardless of selection of option code D1, D3 or D4.Pure nitrogen gas is used for oil-prohibited use (option codes K1, K2, K5, and K6).
