Install Cover
18. Apply a film of grease to the exposed surface of the housing o-ring (on base). Place
the Dual Probe Holder cover on the base, and hand tighten. Be sure to turn an
additional 1/2 turn to seat the enclosure seal.
Wiring Considerations
• There are three wiring holes machined in the base of the Dual Probe Holder to pass
cabling through. If a wiring hole is not needed, use a 3/4 inch plug to close the
opening. The plug will maintain a NEMA 4X rating for environmental protection.
• The field wiring must be enclosed in 3/4 inch conduit. The conduit must be sealed at
the cable entry to maintain a NEMA 4X rating.
• Protect cable ends from debris before pulling through conduit.
• Terminate the shielded wires at the monitor end to prevent ground loops.
Refer to the wiring requirements in the eddy current probe manual and the Allen-Bradley
9000 series sensor manual. In addition, refer to the monitor manual in which the sensors are
connected to for requirements specific to the monitor.
Replacing the Sensors in Dual Probe Holder
The Dual Probe Holder allows removing and installing of the sensors without disassembling
the machine. Follow the steps below to remove the sensors from the Dual Probe Holder.
Replacing Non-Contact Sensor

1. Remove the Dual Probe Holder cover.
2. Disconnect the probe lead from the extension cable.
3. Tighten the adjusting knob to hold the sensor away from the target.
