2. Remove the rear cap. If a plug connector is installed in the rear cap, slide
it out.
3. Using a 3/8 inch wrench, carefully unscrew the exposed delrin nut (the
back end of the probe). When
all the threads are free, pull the
probe out of the cylinder.
PFC Probe Replacement Instructions
Examine the condition of the probe. If debris from the application’s environment
or from dirty air lines covers the probe, the wiper and rod inside the cylinder are
most likely contaminated as well, and replacing the entire cylinder is
recommended. If only a new probe is installed, its life will be shortened.
