Fisher® 646 electro-pneumatic transducers use a patented 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. Small size. Vibration resistance. High output capability. Low air consumption.

Features & Benefits
Small Size—The small size and light-weight design of the transducer facilitate mounting and provide improved space utilization.
Vibration Resistance—The transducer, used in a standard valve/actuator mounted application, exhibits an output shift of less than 1 percent of span when tested to SAMA Standard PMC 31.1, Condition 3.
High Output Capability—The output volume of the transducer is adequate to drive valve/actuator combinations without requiring a positioner or volume booster.
Low Air Consumption—The transducer has low air consumption which cuts operating costs.
Easy Maintenance—Modular design of the converter allows easy replacement in the field for reduced maintenance costs.
Superior Performance—The accuracy, linearity, and frequency response coupled with minimal hysteresis far exceed the requirements of most control systems.
