Product Introduction
The Bently Nevada 330171-00-10-10-02-05 is a 3300 XL 8 mm proximity probe with integral cable, used in eddy-current shaft vibration and displacement measurement systems. It works together with a 3300 XL 8 mm Proximitor sensor to form a complete transducer system.
The model code breaks down as follows:
| Segment | Value | Meaning |
|---|---|---|
| Base model | 330171 | 3300 XL 8 mm probe with integral cable |
| Option | 00 | Standard option |
| System length | 10 | 1.0 m (3.3 ft) integral cable length |
| Thread / mounting | 10 | Standard thread / mounting option |
| Sensitivity | 02 | Standard 200 mV/mil (7.87 V/mm) |
| Approval | 05 | Multi-license approval |
This probe is typically installed on fluid-film bearing machinery such as steam turbines, centrifugal compressors, gas turbines, generators, and large pumps. It measures the gap between the probe tip and the rotating shaft surface, producing a voltage signal proportional to that gap. The system can monitor shaft radial vibration, axial thrust position, eccentricity, and keyphasor reference.
The 330171 series probe has an integral cable, meaning the cable is permanently attached to the probe body. Unlike separate probe-plus-extension-cable configurations, it cannot be split into individual components. It must be paired with a compatible 3300 XL 8 mm Proximitor sensor.

Quality Control Process (DYNAMIC GENERATION)
- Part-number verification: Confirm 330171-00-10-10-02-05 on the probe label or packaging.
- Visual inspection: Check the probe body, integral cable jacket, and connector for cracks, crushing, or chemical damage.
- Probe tip inspection: Verify the sensing face is free of scratches, coating damage, or contamination.
- Connector check: Inspect the ClickLoc or compatible connector for pin damage, seal integrity, and thread condition.
- Continuity test: Verify probe coil resistance and cable continuity if test equipment is available.
- System match check: Confirm the probe sensitivity (200 mV/mil) and system length match the connected 3300 XL Proximitor sensor.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not confuse 330171 with 330103/330105/330106. The 330171 is a probe with integral cable, while 330103/330105/330106 are probes designed to be used with separate extension cables. They are not directly interchangeable without verifying system length and connector compatibility.
❗ Verify the system length. The “10” in the model code indicates a 1.0 m integral cable. Substituting a different length (e.g., 5.0 m or 9.0 m) may affect routing and mechanical fit.
❗ Match the sensitivity. The “02” option means 200 mV/mil (7.87 V/mm). Using a probe with different sensitivity will cause measurement errors unless the Proximitor sensor is configured accordingly.
❗ Confirm the approval suffix. The 05 approval option denotes multi-license approval. Substituting 00 (no approval) or CN may affect hazardous-area or regional compliance requirements.
❗ This is not a casing vibration transmitter. The 330171 measures shaft relative vibration, not casing vibration. It should not be substituted for 177230 seismic transmitters or velocity sensors.
❗ Check the gap voltage during installation. For 8 mm probes, the typical target gap voltage is approximately −10.0 VDC, corresponding to a recommended installation gap of about 1.27 mm. Incorrect gap setting will cause measurement errors or false alarms.
