Feedback unit, intrinsically safe/explosion proof

For position feedback, the F5 unit offers the ability to very simply add switches (mechanical or proximity), a potentiometer or a 4-20 mA transmitter to the P5 base pneumatic positioner. The IP66 modular housing needs no special mounting pieces and is O-ring sealed. F5 mounts direct on top of P5/EP5 positioner. LED lights assist when calibrating the transmitter. The cam and spindle are not splined, so true 100% resolution is achieved - an important feature when used on control valves.
Available in standard, Intrinsically safe and Explosion proof versions.
