Type 3660 and 3661 Positioners

Accurate, Efficient, Vibration-Resistant Operation—Positioner design provides accurate, fast-responding instruments able to withstand the vibrations of most plant environments. Low steady-state air consumption contributes to efficient operation.
Variable Gain—Easily adjustable gain and damping adjustments fine tune the positioner stability to specific application requirements.
Versatility—Positioner accepts a standard pneumatic input signal (Type 3660) or a standard milliampere dc input signal (Type 3661) from a control device. This positioner provides split range capabilities and adjustable zero and spans.
Fewer Spare Parts Required—The Type 3660 and 3661 positioners are basically interchangeable, requiring fewer spare parts to support these positioners.
Easy Positioner Adjustments—Zero and span adjustments can be made with the cover in place.
Rugged Construction—The case and cover are designed to withstand mechanical vibration and rough handling.
Control Valve Diagnostic Testing Capability—To support diagnostic testing of valve/actuator/positioner packages with the FlowScanner valve diagnostic system, connectors, piping, and other hardware can be installed between the Type 3660 or Type 3661 positioner and the actuator.
