Optional codes
/□ Optional specification
The ‘6’ marks indicate the most typical selection for each specification. Example: EJA130A-DMS-92NA/□
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of SUS316 material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
*1: Indicates material of cover flange. Material of process connector is SCS14A(SUS316 equivalent).
*2: Diaphragm material is Hastelloy C-276 or ASTM N10276. Other capsule wetted parts materials are SUSF316L, SUS316L or ASTM grade 316L.
*3: If necessary, specify Mounting bracket code C, D or K.
*4: If necessary, specify Mounting bracket code A, B or J.
*5: Lower limit of ambient and process temperature is —15°C.
*6: Not applicable for Output signal code F and G.
*7: 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.
*8: SUS316 or ASTM grade 316.
