3660 and 3661 PositionersFisher 3660 pneumatic and 3661 electro pneumaticsingle acting Positioners are part of the 3660 series ofpositioners. They are used with various actuators onsliding stem valves for throttling applications. Theserugged Positioners provide a valve positionproportional to a pneumatic input or a standardmillampere DC input signal received from a Accurate, Efficient, Vibration ResistantOperation positioner design provides accurate,fast responding instruments able to withstand thevibrations of most plant environments. Lowsteady state air consumption contributes toefficient Variable Gain Easily adjustable gain and dampingadjustments fine tune the positioner stability tospecific application Versatility positioner accepts a standardpneumatic input signal (3660) or a standardmilliampere DC input signal (3661) from a controldevice. This positioner provides split rangecapabilities and adjustable zero and Fewer Spare Parts Required Most of the parts for3660 and 3661 Positioners are interchangeable,requiring fewer spare parts to support Rugged Construction The case and cover aredesigned to withstand mechanical vibration andrough 3660 positioner withBaumann Valve and Actuatorn Easy positioner Adjustments Zero and spanadjustments can be made with the cover in Control Valve Diagnostic Testing Capability Tosupport diagnostic testing ofvalve/actuator/positio
