The use of inappropriatematerials can result in the leakage of corrosiveprocess fluids and cause injury to personnel and/or damage to plant facilities. It is also possible thatthe diaphragm itself can be damaged and thatmaterial from the broken diaphragm and the fillfluid can contaminate the user’s process fluids.Be very careful with highly corrosive processfluids such as hydrochloric acid, sulfuric acid,hydrogen sulfide, sodium hypochlorite, and hightemperaturesteam (150 ºC [302 ºF] or above).Contact Yokogawa for detailed information of thewetted parts material.*2: Air connections, drain plug connection are also tappedfor ANSI NPT threads in addition to the processconnection.2.5 OptionsAir Set:Fixed combination pressure regulator and filterwith 35 mm diameter pressure gauge mountedand piped to transmitter.
