Model 77 Current-to-Pneumatic Transducer
The Model 77 Current-to-Pneumatic Transducer, designed specifically for measuring circuits, converts the output of an electronic measuring device to a pneumatic signal.Model 771 Current-to-Pneumatic Transducers
The Model 771 Current-to-Pneumatic Transducersdesigned as a cost-effective valve service transducer. The Model 771 receives the output of an electronic signal, such as a PID control function, and drives a control valve via the transducer until the control function is satisfied.
Features and Benefits
High signal sensitivity for demanding applications
Simplified design ensures simplified operation
Rugged, NEMA construction, with insensitivity to shock, vibration, and supply pressure variations, accommodate operation in harsh industrial environments
Choice of output capacities provides application versatility
