Optional codes
/  Optional specication
The “►” marks indicates the most typical selection for each specication. Example: EJX630A-DAS4N-012NN/.
*1: Hastelloy C-276 or ASTM N10276.
*2: Not applicable for combination of capsule code D and wetted parts material code H.
*3: Not applicable for output signal code F.
*4: Users must consider the characteristics of selected wetted parts material and the inuence 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’fs process uids.
Be very careful with highly corrosive process uids such as hydrochloric acid, sulfuric acid, hydrogen sulde, sodium hypochlorite,
and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material.
*5: Not applicable for electrical connection code 0, 5, 7 or 9.
*6: Material of a blind plug is aluminum alloy or 304 SST.
*7: Not applicable for output signal code G.
# The ‘#’ marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of 316
SST material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
