The 3300 XL 8 mm proximity transducer family is used for non-contact shaft vibration and position measurement in rotating machinery monitoring. Maintenance teams may search for this probe when a measurement channel becomes unstable, shows an abnormal reading, loses its signal, or requires replacement after physical damage.
An unreliable channel can reduce visibility into machine condition and delay fault assessment. Check the complete measurement chain before concluding that the probe itself is defective.
| Inspection Point | What to Confirm |
|---|---|
| Ordering code | Compare the full part number and coded dimensions with the installed probe. |
| Signal-chain configuration | Confirm the Proximitor Sensor and any extension cable match the intended system arrangement. |
| Mounting and routing | Check thread fit, mounting clearance, cable routing and bend radius. |
| Connector and cable | Inspect for visible damage, looseness or contamination before recommissioning. |
| Abnormal signal | Consider the probe, cable, sensor, target and monitor channel during fault isolation; symptoms alone do not identify the failed component. |
Include these details to help confirm the item and delivery terms.

Confirm the M10 × 1 thread, 70 mm case-length option, 1.0 m total probe-length option and connector/cable code against the installed part.
No. The probe is a component of the proximity transducer system. Confirm the compatible Proximitor Sensor and any required extension cable for the installation.
Not from the reading alone. Inspect the probe, cable, sensor, target and monitor channel as part of fault isolation.
Match the complete ordering code and verify mechanical fit, cable routing, connector condition and the installed transducer-system configuration.
Consult the Bently Nevada 3300 XL 8 mm Proximity Transducer System datasheet, document 141194, and compare its ordering-code table with the complete part number.
