Features

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.Easily adjustable gain and damping adjustments fine tune the positioner stability to specific application requirements.Positioner accepts a standard milliampere DC input signal from a control device. This positioner provides split range capabilities and adjustable zero and spans.Most of the parts for 3661 positioners are interchangeable; requiring fewer spare parts to support these positioners.The case and cover are designed to withstand mechanical vibration and rough handling.Zero and span adjustments can be made with the cover in place.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 3661 positioner and the actuator.
