Fisher 846 Electro-Pneumatic Transducer

Fisher 846 transducer converts an electrical output signal from a controller to a pneumatic signal necessary to operate a control valve actuator or pneumatic positioner. Using electronic feedback, the transducer can correct for error-producing effects, such as variations in supply pressure and downstream leakage.

Features

• The Fisher 846 low-mass pilot stage, mechanically damped deflector bar, and rugged construction provide stable performance in vibration.
• Major mechanical and electrical components are incorporated into a single field-replaceable master module.
