From a compliance perspective, you do not need to install the ferrites if the cable is in a
ferromagnetic conduit (such as galvanized steel) because this type of conduit provides
additional shielding. Note that the conduit entry of the device is ½ inch NPT. If you install
ferrites with a conduit, you will need a wider conduit ( ¾ inch NPT or M20) to
accommodate the ferrites and an adapter is required at the conduit entry of the device.
The ferrites provided with the sensors that have standard (polyurethane) cables are Fair-
Rite P/N 0431173951. These ferrites simply snap onto the cable near the point where the
cable enters the transmitter housing. You can also use wire ties and/or heat-shrink with
these ferrites.
The ferrites provided with the sensors that have armor-jacketed cables are Fair-Rite P/N
2631665702. These slide onto the cable and must have wire-ties and/or heat-shrink, or
some similar mechanism, to hold them in place.
