GPE - Model 31490 -Rotary Position Transmitter

The Model 31490 Rotary Position Transmitter is a potentiometer type transmitter which transmits field information to a remote point. The Model 31490 Rotary Position Transmitter is used principally as a feedback for valve actuators. The 31490 accepts a shaft position and produces a 4-20mA electrical output signal over a 2 wire system. The signal from shaft rotation is produced by a potentiometer. The shaft of the potentiometer is connected to the transmitter input shaft through a stepdown gear. The 4-20mA is generated by a constant current generator. The transmitter is housed in an aluminum, weatherproof and explosion proof housing built to Class I, Division I, Group D requirements of Factory Mutual. Temperature Range is from -30°F to +140°F.
