The‘☆’marks indicate the most typical selection for each specification.Example: EJA220A-DMSA12G5A-92NN/
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use ofSUS316 material,there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
*1：Low pressure side wetted parts material: Cover flange; SCS14A, Process connector; SCS14A,Capsule; SUS316L(Diaphragm, Hastelloy C-276 or ASTM N10276), Vent plug; SUS316
*2：Applicable for 4-inch (100 mm) flange size (Process flange size/material G, H and J).
*3：Applicable for 3-inch (80 mm) flange size (Process flange size/material D, E and F).
*4：Not applicable for Output signal code F and G.
*5：Users must consider the characteristics of selected wetted parts material and the influence of process fluids.Theuse 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.
*6：Hastelloy C-276 or ASTM N10276.
*7：Not applicable when option code /E1 is specified.
*8：SUS316 or ASTM grade 316.
*9：SUS304 or ASTM grade 304. Forged version may be used.
*10：SUS316 or ASTM grade 316. Forged version may be used
