sure transducer all-inclusive design provides users with eld
accessible ranging, choice of output and eld zeroing.
Choose from three congurable pressure transducers: 5 up
to 50 psid, 10 up to 100 psid, or 25 up to 250 psid. Each Model
231 has 4 unidirectional and 4 bidirectional switch selectable
pressure ranges and can be recongured in the eld for 0-5

231 jumper selectable port swap feature eliminates costly
replumbing if the pressure transducer is improperly installed
or replaced. An optional LCD display is available for on-site
indication of line and dierential pressure.
