Product Introduction
The Bently Nevada 330106-05-30-10-02-CN is an 8mm reverse-mount proximity probe from the 3300 XL family. Unlike standard forward-mount probes, the reverse-mount design allows the probe to be installed from the back side of the mounting bracket, making it suitable for installations with limited front access or tight mechanical clearances.
This probe generates a high-frequency electromagnetic field at its tip. When positioned near a conductive shaft surface, eddy currents are induced, and the resulting change in coil impedance is converted into a DC voltage signal proportional to the gap between the probe tip and the target. This enables precise measurement of both static displacement and dynamic vibration without physical contact.
The 3300 XL 8mm system is designed to work with 3300 XL extension cables and 3300 XL Proximitor Sensors (such as 330180-50-00 or 330180-51-00), and it interfaces with Bently Nevada 3500 monitoring modules including 3500/40M, 3500/42M, 3500/45, and 3500/25. The system meets API 670 requirements for mechanical vibration monitoring.

Quality Control Process (DYNAMIC GENERATION)
- Part-number verification: Confirm 330106-05-30-10-02-CN on the probe label or packaging.
- Visual inspection: Check probe tip, PPS encapsulation, stainless steel body, cable jacket, and ClickLoc connector for damage, cracks, or corrosion.
- Cable integrity check: Inspect the 1.0m cable for cuts, crushing, moisture ingress, or connector pin damage.
- Dimensional verification: Confirm body length matches the 30mm configuration and thread is M10×1.
- Electrical verification: Test probe continuity and insulation resistance; verify output with a compatible proximitor if test equipment is available.
- System compatibility check: Confirm the probe matches the installed extension cable length, proximitor model, and 3500 monitor configuration.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Do not confuse reverse-mount with forward-mount probes. 330106 is a reverse-mount probe. Substituting a standard forward-mount probe such as 330103 or 330104 may result in incorrect mechanical fit and installation failure.
❗ Match the full order code. The suffix 05-30-10-02-CN defines thread, body length, cable length, connector type, and approvals. Substituting a different code such as 05-30-05-02-00 or 05-30-10-02-00 may change cable length or certification status.
❗ Verify system length. The total system length must include probe cable, extension cable, and cable to proximitor. Mismatched lengths can degrade linearity and measurement accuracy.
❗ Do not mix XL and non-XL components without verification. Although 3300 XL 8mm probes are backward compatible with many 3300 components, the full system should be validated against Bently Nevada interchangeability rules.
❗ Confirm CN approval requirement. The CN suffix indicates a specific approval option. Replacing it with a different approval code may affect compliance with site or regional certification requirements.
❗ Treat as a protection-critical sensor. Incorrect gap setting, damaged cable, or wrong proximitor pairing can cause false alarms or missed trips on turbines and compressors.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| Bently Nevada 330106-05-30-10-02-CN | Same 330106-05-30-10-02-CN probe | Direct | Match full order code and system length. |
| Bently Nevada 330106-05-30-10-02-CN | Other 330106 variants | Needs Verification | Confirm cable length, body length, connector type, and approvals. |
| Bently Nevada 330106-05-30-10-02-CN | 330103 / 330104 forward-mount probe | Not direct | Different mounting direction; mechanical fit will not match. |

Benchmarks:
- 3300 XL 8mm reverse-mount proximity probe for eddy-current vibration and displacement measurement.
- M10×1 thread, 30mm body length, 1.0m cable, ClickLoc connector, CN approval option.
- Compatible with 3300 XL extension cables, 330180 proximitor sensors, and 3500/40M, 3500/42M, 3500/45, and 3500/25 monitors.
- Suitable for radial vibration, axial position, differential expansion, eccentricity, and Keyphasor applications.
- Third-party listings that describe 330106 part numbers as 3500 monitor modules or 4-channel displacement monitors are incorrect; the 330106 prefix identifies a reverse-mount proximity probe, not a rack-mounted monitor.
