3730-0 - ELECTRO-PNEUMATIC POSITIONER

توضیحات

The Type 3730-0 electro-pneumatic positioner is a basic control positioner designed to work in general industrial applications. This positioner can work with single-acting linear control valve inherently and double-acting linear control valve with the addition of a reversing amplifier.The basic design of the positioner is tailored for SAMSON control valves with predefined travel spans programable via DIP switch inputs.The potentiometer-based travel sensor of the Type 3730-0 is not susceptible to wear often found in gear-based travel sensors.The travel range of the Type 3730-0 can be restricted up to 1/5 maximum stroke as well as operated in split range.The analog (continuous) pneumatic output prevents pulsing operations in case of leaking actuator.
