Quick Detail

Description

The Bently Nevada 330710-00-05-50-02-05 3300 XL 11 mm Proximity Probe is a premium-grade, eddy-current displacement transducer engineered for mission-critical machinery protection and high-accuracy condition monitoring. This sophisticated 11 mm proximity sensor operates by generating an RF signal that induces eddy currents in a conductive target, producing an output voltage with a precise linear relationship to the gap between its probe tip and the target surface. This fundamental principle empowers it to deliver exceptional performance in both dynamic vibration analysis and static position measurement, establishing it as a cornerstone component for advanced predictive maintenance strategies and rotating asset health management. Its core applications are essential for operational integrity, including continuous monitoring of radial vibration and axial/radial position on fluid-film bearing machinery, accurate rotational speed calculation, and the provision of a reliable Keyphasor® reference signal for phase-based diagnostics.

As a leading model within the renowned Bently Nevada 3300 XL series, this 11 mm eddy current probe is constructed to satisfy the most stringent application demands. The part number "330710-00-05-50-02-05" explicitly defines its configuration, which features an extended 5.0-meter (16.4-foot) integral cable and a streamlined 50 mm overall case length. The probe is manufactured in strict compliance with the American Petroleum Institute (API) 670 Standard, guaranteeing certified performance in terms of mechanical design, extended linear range, thermal stability, and measurement fidelity. This adherence to industry benchmarks cements its reputation as a trusted solution for essential monitoring tasks in oil & gas production, power generation turbines, and heavy industrial manufacturing facilities.

Applications

In large-scale rotating equipment such as steam turbines, gas turbines, centrifugal compressors, and large motors, this 3300 XL 11 mm eddy current probe serves as the core sensor for non-contact vibration and position measurement. Its 4.0 mm (160 mils) wide linear range and excellent temperature stability (-52°C to +100°C) enable it to accurately capture both dynamic shaft vibration (for fault diagnosis) and static position (such as axial thrust position and radial eccentricity), providing critical data for protecting unit safety and enabling predictive maintenance. Its rugged AISI 304 stainless steel case and PPS probe tip material resist oil, steam, and minor particulate washout, ensuring long-term reliability in harsh machinery environments.

This probe is an ideal choice for generating a Keyphasor® reference signal and accurately measuring rotational speed. By monitoring the passage of a gear tooth, keyway, or shaft marker, it produces a once-per-revolution pulse. This signal is essential for phase analysis, balance corrections, and synchronized data acquisition, helping engineers correlate vibration sources with rotational position. The standard 5.0-meter cable length and miniature coaxial ClickLoc connector with protector facilitate medium-to-long-distance wiring from the machine to the monitoring system and ensure a secure, vibration-resistant connection.

With its 50 mm overall case length and standard 0 mm unthreaded length design, this probe is well-suited for installations where space is relatively confined but a larger measurement range is required. Compared to an 8 mm probe, the 11 mm diameter provides a larger sensing area and a wider linear range, making it applicable for monitoring shaft displacement in large bearings (e.g., guide bearings in hydroelectric generators) or heavy-duty gearboxes. Its full compliance with the API 670 Standard makes it a compliant and reliable choice for greenfield projects or legacy system upgrades in heavily regulated industries like oil & gas and power generation.

Specifications

Competitive Advantage

1.Superior Measurement Performance & Industrial Standard Compliance

This 3300 XL 11 mm probe offers an extensive 4.0 mm linear measurement range, providing outstanding performance for monitoring large-displacement conditions. Its design and manufacturing strictly adhere to the API 670 Standard, meeting the highest industry specifications for mechanical form, temperature effects, output linearity, and overall reliability. This offers certified assurance for critical machinery protection, reducing the risk of unplanned downtime due to substandard sensor performance.

2.Robust Environmental Ruggedness & Durable Construction

The probe features a full AISI 304 stainless steel housing and a wear-resistant PPS (Polyphenylene Sulfide) probe tip, delivering exceptional resistance to corrosion, oil contamination, and physical abrasion. Its broad operating temperature range (-52°C to +100°C) ensures stable signal output across diverse harsh industrial environments, from freezing outdoor installations to high-heat areas near machinery. This durability significantly extends the probe's service life in demanding applications, lowering the total cost of ownership.

3.Effortless System Integration & Installation Flexibility

As part of the 3300 XL series, this probe is fully plug-and-play compatible with other series components like extension cables and proximitors, eliminating the need for field calibration and simplifying installation and maintenance. The compact 50 mm overall length combined with the standard 5.0-meter cable offers greater flexibility in equipment layout and cabling. Its miniature coaxial ClickLoc connector ensures a quick, reliable, and vibration-resistant connection, while maintaining backward compatibility with select legacy 3300 series systems, protecting existing investments and facilitating straightforward upgrades.
