Frequently Asked Questions

1. What is the 330103-00-02-05-01-00 used for?

It provides continuous, non-contact monitoring of shaft vibration, shaft position, and radial displacement in rotating machinery such as turbines, compressors, motors, and pumps.

2. What is the difference between 330103 and 330101 probes?

The 330103 is the metric version with an M10 × 1 thread, while the 330101 uses 3/8-24 UNF imperial threads.

3. What does the "00" unthreaded length option mean?

It indicates the probe has no unthreaded section, allowing the threaded portion to extend directly to the probe tip.

4. What does the "02" option indicate?

It specifies a 20 mm overall probe case length.

5. What cable length is supplied?

The 05 option provides a 0.5 m (1.6 ft) integral cable.

6. What connector is fitted?

The 01 option specifies a Miniature coaxial ClickLoc® connector with connector protector.

7. What does the final "00" approval code indicate?

It indicates no CSA, ATEX, IECEx, or other hazardous-area approvals are included with this configuration.

8. Is this probe API 670 compliant?

Yes. When used with the appropriate 3300 XL Proximitor® Sensor and extension cable as a complete transducer system, it is designed to meet API 670 requirements.

9. Can it be used with any 3300 XL Proximitor Sensor?

Yes, provided the Proximitor Sensor and extension cable are selected to create the correct calibrated system length specified by Bently Nevada.

10. What are the main advantages of this probe?

It offers high accuracy, excellent repeatability, stable long-term performance, metric mounting compatibility, and reliable non-contact measurement for machinery protection and predictive maintenance.
