Fisher Electro Pneumatic Positioner. Fisher Valve Positioner 582i ElectroPneumatic Converter The 3582i electro-pneumatic positioner, is a modular unit that can be installed at the factory or in the field Low steady-state air consumption contributes to efficient operation.
Fisher 3661 ElectroPneumatic Positioner from www.askalon.com
Conventional pneumatic positioners receive a pneumatic control signal and translate that into the appropriate pneumatic output signal to the control valve actuator These rugged positioners provide a valve position proportional to a pneumatic input or a standard millampere DC input signal received from a control device.
Fisher 3661 ElectroPneumatic Positioner
Legacy processing units may use pneumatic pressure signaling as the control set point to the control valves 3582 pneumatic valve positioners and the 3582i electro‐pneumatic valve positioner shown in figure 1 are used with diaphragm‐actuated, sliding‐stem control valve assemblies The pneumatic valve positioners receive a pneumatic input signal from a control device and modulate the supply pressure to the control valve actuator
Fisher Valve Positioner 582i ElectroPneumatic Converter. 4-20 mA DC constant current with 30 VDC maximum compliance voltage, can be split range Conventional pneumatic positioners receive a pneumatic control signal and translate that into the appropriate pneumatic output signal to the control valve actuator
