Optional codes

/口 Optional specification

The ‘’ marks indicate the most typical selection for each specification. Example: EJA438W-DASA1AA-AA02-92NA/口 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: Refer to GS 01C22T01-00E for HART Protocol version.
*2: In case of Wetted parts material code T (Tantalum), the process temperature limit is -10 to 200 oC.
*3: Wetted parts material code T (Tantalum) cannot be applied.
*4: Even in case where Fill fluid code D (fluorinated oil) is selected, if degrease cleansing treatment or both degrease cleansing and dehydrating treatment for the wetted parts is required, specify Optional code K1 or K5.
*5: In case of Wetted parts material code H (Hastelloy C), T (Tantalum), and U (Titanium) or Fill fluid code C (for high temperature use), specify capillary length from 1 to 5 m.
*6: Refer to GS 01C22T02-00E for Fieldbus communication.
*7: Not applicable for Output signal code F and G.
*8: 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.
*9: Hastelloy C-276 or ASTM N10276.
*10:    Refer to GS 01C22T03-00E for PROFIBUS PA communication.
*11:    JIS SUS316L or ASTM grade 316L.
*12:    JIS SUS304 or ASTM grade 304. Forged version may be used.
*13:    JIS SUS316 or ASTM grade 316. Forged version may be used.
