Optional Codes
¨/ Optional specification
The “►” marks indicate the most typical selection for each specification.
*1: Not applicable for output signal code F.
*2: 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.
*3: Not applicable for electrical connection code 0, 5, 7 and 9.
*4: Material of a blind plug is aluminum alloy or 304 SST.
*5: Only applicable for Wetted parts material code S.
*6: Not applicable for measurement span code F.
*7: Not applicable for electrical connection code 0, 5, 7, 9 and A. Content rate of copper in the material is 0.03% or less and
content rate of iron is 0.15% or less.
