Bently Nevada 330101-00-16-10-02-00 3300 XL 8mm Proximity Probe

The Bently Nevada 330101-00-16-10-02-00 is a 3300 XL 8mm proximity probe featuring a 1.0-meter cable and a 1.6″ threaded case. It provides high-accuracy vibration and displacement monitoring for critical rotating machinery.

Technical Specification Overview

The Bently Nevada 330101-00-16-10-02-00 functions as a high-precision, non-contacting transducer within the 3300 XL 8mm Proximity Transducer System. This sensor generates an eddy current field to measure the microscopic gap between the probe tip and a rotating metal shaft. By converting mechanical displacement into a proportional voltage signal, it allows the 3500 Monitoring System to track shaft vibration and axial position with sub-millimeter resolution. Consequently, this probe provides the primary data required for critical machinery protection and diagnostic analysis.

Design and Functional Capabilities

Engineers designed this specific probe configuration with a 3/8-24 UNF threaded body and a 1.0-meter integral cable. This model features a 1.6-inch overall case length with no unthreaded portion, making it a standard choice for direct mounting through bearing housings. Furthermore, the 3300 XL series incorporates advanced thermal stability features, ensuring that the sensor maintains a consistent scale factor even during the extreme temperature fluctuations typical of turbine startups and full-load operations.

Operational Impact and Industrial Applications

This proximity probe actively drives predictive maintenance strategies by delivering a continuous stream of high-fidelity machinery health data. Consequently, plant operators can identify mechanical faults such as rotor imbalance, shaft misalignment, or bearing degradation before they escalate into catastrophic equipment failure. Moreover, the 3300 XL system is fully compatible with Bently Nevada’s System 1 software, enabling deep-dive diagnostic capabilities and automated asset condition monitoring.

Primary industrial applications include:

Radial Vibration: Monitoring the dynamic orbit and movement of shafts in centrifugal compressors and pumps.
Axial Position: Tracking the thrust displacement of rotors in high-speed steam and gas turbines.
Keyphasor Signals: Providing a phase reference pulse to synchronize vibration data with rotational speed for balancing and diagnostic plotting.

Mechanical Integrity and Environmental Resilience

To ensure maximum durability in punishing atmospheres, Bently Nevada utilizes a 304 stainless steel case and a PPS (polyphenylene sulfide) resin tip. This construction creates a hermetic seal that resists the ingress of oil, moisture, and steam. Additionally, the patented ClickLoc connector technology provides a secure, vibration-resistant electrical path. This locking mechanism prevents the signal attenuation that often occurs when standard connectors loosen due to the high-frequency mechanical oscillations typical of industrial bearing housings.
