Fisher 646 Electro-Pneumatic Transducer
The Fisher 646 electro-pneumatic transducer uses a converter module that converts a 4 to 20 milliampere input signal to a proportional 0.2 to 1.0 bar (3 to 15 psig) pneumatic output signal. The converter module uses small parts of minimum mass, which are balanced symmetrically around a pivot point at the center of the mass. This balanced arrangement results in a high performance instrument that reduces sensitivity to vibration.
Features
The small size and light-weight design of the transducer facilitate mounting and provide improved space utilization.
The output volume of the transducer is adequate to drive valve/actuator combinations without requiring a positioner or volume booster.
The transducer has low air consumption, which lowers operating costs.
Modular design of the converter allows easy replacement in the field for reduced maintenance costs.
