Bently Nevada 330104-00-08-10-01-05 8 mm Proximity Probe

Product Description

The 330104-00-08-10-01-05 from Bently Nevada is an 8 mm proximity probe engineered for precise, non-contact measurement of shaft vibration, displacement, and position in critical rotating equipment. As a core component of the 3300 XL Proximity Transducer System, this probe operates using eddy-current technology to deliver highly stable and repeatable signals under continuous industrial operation.

Designed with an 80 mm stainless-steel housing and an integral 1.0 m low-noise cable, the probe connects to a compatible 3300 XL Proximitor® sensor via a miniature ClickLoc® coaxial connector. When paired with the correct extension cable and Proximitor® module, the system produces a calibrated output voltage directly proportional to the probe-to-target distance, supporting both static and dynamic measurements.

The 330104-00-08-10-01-05 carries CSA, ATEX, and IECEx approvals, making it suitable for use in hazardous areas where reliability and compliance are mandatory. It is commonly installed in machinery protection systems that conform to API 670 requirements.

Functional Role in the 3300 XL System

Within a complete 3300 XL transducer loop, the 330104-00-08-10-01-05 probe enables accurate monitoring of critical machine parameters, supporting early fault detection and protective shutdown logic. Typical measurement functions include radial vibration, axial thrust position, and reference inputs for phase or speed monitoring when used in appropriate configurations.

Typical Applications

This proximity probe is widely deployed in high-value rotating assets such as steam and gas turbines, centrifugal and axial compressors, large pumps, electric motors, and industrial gearboxes. Its stability and certification make it suitable for both general-purpose and hazardous-area installations.

Frequently Asked Questions

Q: Can this probe be used alone without other components?
A: No. Proper operation requires a matched 3300 XL extension cable and a compatible 3300 XL Proximitor® sensor to maintain system calibration.

Q: Is the probe interchangeable with other 8 mm 3300 XL models?
A: Functionally yes, but mechanical dimensions, cable length, and approvals differ. Always verify part number compatibility with the installation drawing and system requirements.
