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.
- Case, components, and gasket materials withstand harsh environments.
- With EPDM O-rings and input module diaphragm, 3720 positioners can be used in low temperature applications.
- With the cover removed, all internal components are easily accessed.
