Quick Detail

Description

The 330103-00-05-10-02-CN represents a specialized, high-performance configuration within the globally recognized 3300 XL 8 mm Proximity Probes family by Bently Nevada. This specific model is a non-contacting, eddy current-based displacement transducer designed for the rigorous demands of industrial vibration monitoring. Engineered with a 0 mm unthreaded length and a compact 50 mm overall case length, this 3300 XL 8 mm Proximity Probe is the premier choice for mounting in tight, space-constrained bearing housings or machine casings where a flush-mount profile is required. The probe tip is manufactured from high-durability Polyphenylene Sulfide (PPS), ensuring the sensor remains impervious to the harsh chemical environments often found in steam turbines and industrial gearboxes.

A defining characteristic of these 3300 XL 8 mm Proximity Probes is the 1.0-meter (3.3 feet) total length integrated cable, which features the proprietary Miniature coaxial ClickLoc connector. This connection technology prevents accidental loosening due to intense mechanical vibration, a critical factor in maintaining system integrity for "Category 1" machinery. Furthermore, the 330103-00-05-10-02-CN carries the -CN suffix, indicating it is explicitly certified for hazardous area deployment under NEPSI (China) standards, alongside international CSA, ATEX, and IECEx approvals. This allows for seamless integration into high-risk petrochemical and gas processing facilities where explosive atmospheres are a constant concern.

Applications

The 330103-00-05-10-02-CN is primarily applied in Radial Vibration Monitoring for high-speed rotating shafts. Its 50 mm compact case design allows it to be installed directly into the bearing caps of pumps, motors, and fans. By capturing minute dynamic displacements within its 2 mm linear range, it enables vibration engineers to detect incipient faults such as rotor unbalance, shaft misalignment, or bearing clearance issues before they lead to equipment damage.

In Axial (Thrust) Position Monitoring, this 3300 XL 8 mm Proximity Probe provides a critical measurement of the shaft's longitudinal movement relative to the thrust bearing. This is essential for preventing rotor-to-stator contact in steam and gas turbines. The probe's 0 mm unthreaded length ensures it can be adjusted precisely to the required gap setting, providing a stable voltage output that represents the exact axial location of the machinery's rotating assembly.

This probe is also widely used for Keyphasor Reference and rotational speed measurements. By detecting a once-per-turn event such as a keyway or notch, the 330103-00-05-10-02-CN generates a pulse signal used for phase analysis and balancing procedures. Its NEPSI/ATEX/IECEx certifications make it the standard choice for speed measurement in hazardous zones within refineries and offshore platforms, ensuring compliance with API 670 safety standards.

Specifications

Competitive Advantage

1. Specialized NEPSI and Global Hazardous Area Approvals

The -CN designation signifies that this probe meets the specific safety requirements for the Chinese market (NEPSI), while maintaining CSA, ATEX, and IECEx certifications. This multi-agency approval allows global engineering firms to standardize on a single probe model for international projects, ensuring safety compliance across different regulatory jurisdictions without the need for hardware changes.

2. Optimized Compact "Flush-Mount" Geometry

With a 0 mm unthreaded length and a 50 mm case, this probe offers maximum installation flexibility in dense machinery layouts. It can be fully threaded into a mounting port, allowing the tip to be positioned perfectly relative to the target while occupying minimal exterior space. This is a significant advantage over longer probes when working in confined industrial environments.

3. High-Integrity ClickLoc Connector System

The Miniature coaxial ClickLoc connector provides a superior mechanical and electrical connection compared to standard threaded alternatives. The gold-plated contacts and positive-locking mechanism ensure that signal resistance remains stable (45 Ω typical) and the connection remains secure even when subjected to the high-frequency vibrations of rotating machinery, reducing the risk of signal "noise" or false alarms.
