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
