Product Description

Product Description

Fisher 846 Electro-Pneumatic Transducer 

The Fisher 846 Electro-Pneumatic Transducer is a reliable, high-performance instrument designed to convert electrical signals into proportional pneumatic outputs for industrial control systems. Manufactured by Emerson, this transducer bridges the gap between electronic controllers and pneumatic actuators, ensuring precise and stable signal transmission in harsh process environments. Its robust design and versatile functionality make it a critical component in applications requiring accurate pneumatic control, diagnostics, and long-term durability

The Fisher 846 electro-pneumatic transducer is rugged, field- mountable transducer that accepts an electrical input signal and converts it to a pneumatic output signal. Typically, the 4 to 20 mA is converted to 0.2 to 1.0 bar (3 to 15 psi).

Fisher™ 846 Electro-Pneumatic Transducer

Features

The low-mass pilot stage, mechanically damped deflector bar, and rugged construction provide stable performance in vibration.
Large diameter nozzles, free-flow pilot stage design, and large internal pneumatic supply passages provide excellent tolerance to reducing the effects of contaminant build-up and erosion.
The electronic feedback control network monitors the pneumatic output signal, detects any input-output deviations and corrects them.
Major mechanical and electrical components are incorporated into a single field-replaceable master module.
With Stroke Port, a constant bleed from the pilot stage vents through a hole in the module cover. Covering the hole increases the transducer output to confirm the proper operation of the pilot and booster stages and stroke the actuator.

Applications

The Fisher 846 Transducer is widely used in industries requiring reliable conversion of electrical signals to pneumatic control for valves and actuators:

Oil & Gas: Wellhead control, pipeline regulation, and offshore platforms.
Chemical & Petrochemical: Process control in reactors, distillation columns, and mixing systems.
Power Generation: Steam turbine control, boiler feedwater systems, and combustion control.
Water/Wastewater: Pump control, treatment plants, and irrigation systems.
Mining & Metals: Heavy-duty applications in conveyor systems and material handling.
Food & Beverage: Hygienic processes with non-corrosive material options.
