Fisher 3720 Electro-Pneumatic Positioner
Fisher 3720 electro-pneumatic positioners are designed for use with either diaphragm or piston rotary actuators. These positioners provide a valve ball or disk position for a specific input signal. The 3720 is created by the addition of a Fisher 3722 electro-pneumatic converter to the 3710 positioner. The positioner provides a valve position in response to a DC current input signal and can easily be configured as single- or double-acting for rotary actuators.
Features
1.Case, components, and gasket materials withstand harsh environments.
2.With EPDM O-rings and input module diaphragm, 3720 positioners can be used in low temperature applications.
3.With the cover removed, all internal components are easily accessed.
4.Changes in supply pressure and ambient temperature have minimal effect on positioner operation.
