Mfr. Part #: 950-ACA
ID #: 30559
The Type-950XP Explosion-proof I/P (current to pressure) transducer produces a pneumatic output that is directly proportional to a current input signal. A closed loop pressure feedback control system provides a highly accurate, stable air pressure output for the operation of actuated valves. The unit can mount in any position and is vibration insensitive. Its compact housing and easily accessible ports and adjustments make setup and installation of the unit simple. An integral volume booster provides high flow capacity, which increases control speed in critical applications.
