/ Optional specification
The “►” marks indicate the most typical selection for each specication. Example: EJX118B-LMSCG-97JDN-WA18B1SW40-BA25/□
EJX438B-LASCG-97JDN-WA18B1SWD0-BA25/□
*1: See table 10-3 ‘Gasket contact surface.’
*2: When specied ushing connection ring code 3, 4, C, or D, exclusive gasket is provided for transmitter side.
*3: Even in case where ll uid code D (uorinated oil) is selected, if degrease cleansing treatment or both degrease cleansing and
dehydrating treatment for the wetted parts is required, specify option code K1 or K5.
*4: Not applicable for gasket contact surface code 1.
*5: Users must consider the characteristics of selected wetted parts material and the inuence of process uids. The use of
inappropriate materials can result in the leakage of corrosive process uids 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 ll uid
can contaminate the user’s process uids.
Be very careful with highly corrosive process uids such as hydrochloric acid, sulfuric acid, hydrogen sulde, sodium hypochlorite,
and high-temperature steam (150˚C [302˚F] or above). Contact Yokogawa for detailed information of the wetted parts material.
