Product Details
The 3610J or 3610JP pneumatic positioner incombination with the Fisher 3622 electro-pneumatic
converter becomes the 3620J or 3620JP positioner,respectively. This integral electro-pneumatic
converter, can be factory installed or installed in thefield on existing positioners. The electro-pneumatic
converter receives the DC current input signal andprovides a proportional pneumatic output signal
through a nozzle/flapper arrangement.The output signal from the converter becomes the
input signal pressure to the pneumatic positioner,eliminating the need for a remote mounted
transducer.The positioner mounts on the actuator as shownbelow. Figure 1 shows the cam feedback
mechanismfor a positioner mounted on the actuator. Positionerbleed air continually purges the enclosure
containingthe feedback lever and the feedback linkages.
