The 148722-01 is 3300 XL Test Plug. The 3300 XL Test Plug has three self contained test pins attached to three color-coded wires 1 metre in length, each terminated in a banana plug. The three-pin adapter plugs into the test pin holes on 3300 XL-style Proximitor sensors. It is used to check the performance of the Proximitor sensor from the test pin holes in the terminal strip without requiring the removal of the field wiring.
Non-Disruptive Loop Testing
Rapid Troubleshooting & Fault Isolation
Error-Proofing & Short-Circuit Prevention
The 148722-01 interconnect test cable is a specialized maintenance tool for the Bently Nevada 3300 XL eddy current system, enabling zero-downtime, wire-free electrical verification of proximitor sensors. Its 3-pin rigid polarized plug connects directly to the sensor terminal block, eliminating the need to disconnect wiring and allowing for safe, rapid validation of OUT, VTX, and COM channels without the risk of miswiring or loosening terminal screws. Equipped with a 1.0-meter cable ending in 4mm insulated banana plugs, this component interfaces seamlessly with portable multimeters and oscilloscopes to check DC gap voltage or AC vibration signals. It facilitates quick, precise isolation of faults—whether originating from the probe, extension cable, or monitor module—making it an essential tool for troubleshooting and verifying industrial machinery monitoring loops.

Fossil Fuel Power Generation
Fast checking the static gap voltages of radial shaft vibration and axial displacement channels on steam turbine generators during overhauls, ensuring correct trip interlock logic.
Petrochemical & Refining
Safely measuring the shaft attitude angle and rotor orbit voltages of high-speed multistage centrifugal compressor trains inside cabinets without disconnecting wires.
Hydroelectric Power
Regularly debugging the relative vibration signal lines of water-guide and upper-guide bearings on large hydro-generators under varying water heads and flow loads.
Iron, Steel & Metallurgy
Quickly connecting to oscilloscopes to capture dynamic AC/DC vibration waveforms of high-power motor main shafts for analysis of bearing pad wear in dusty, high-EMI blower rooms.
Nuclear Power
Performing safe gap monitoring and secondary loop signal injection calibration without interrupting operation inside Proximitor terminal boxes during nuclear steam turbine start-stops.
Four critical precautions must be observed when using the 148722-01 test plug. First, when inserting or removing the 3-pin head, always push or pull straight and align it with the keyway, and never twist it violently to prevent the pins from snapping. Second, no field wiring removal is required when measuring or injecting signals through this plug, eliminating unnecessary steps that could cause loose terminal connections. Third, the white, red, and black banana plugs at the tail correspond to Signal Out, Power (VTX), and Common Ground (COM) respectively, and must be strictly verified before connection to prevent burning out the internal Proximitor chip. Fourth, it is a portable maintenance tool and lacks long-term high-temperature endurance, waterproofing, or oil-resistance, so it is strictly forbidden to leave it permanently installed in harsh field conditions.
It is a dedicated 3300 XL series Proximitor Sensor test plug, manufactured by Bently Nevada, USA.
