Quick Detail

Description

The 330104-00-10-20-02-05 represents the high-performance benchmark in the 3300 XL 8 mm Proximity Probes series, a premier eddy current displacement transducer system manufactured by Bently Nevada. This specific 3300 XL 8 mm Proximity Probes model is meticulously engineered to provide non-contacting, high-precision gap measurements for critical rotating machinery. By converting the physical distance between the probe tip and a conductive target into a linear voltage signal, the 330104-00-10-20-02-05 allows for real-time monitoring of shaft vibration and axial position. As an essential component of the 3300 XL 8 mm Proximity Probes ecosystem, it ensures that industrial operators can implement robust predictive maintenance and machinery protection strategies.

Technically, this 3300 XL 8 mm Proximity Probes variant features a 100 mm overall case length with a 0 mm unthreaded length, making it ideal for flush-mount or deep-access installation scenarios. The 330104-00-10-20-02-05 is equipped with a 2.0-meter (6.6 feet) total length cable terminated with the innovative Miniature ClickLoc coaxial connector. These 3300 XL 8 mm Proximity Probes are built in strict accordance with the API 670 standard, guaranteeing exceptional linearity and signal stability across a wide temperature range. The probe tip is molded from high-tech Polyphenylene Sulfide (PPS), while the rugged housing utilizes AISI 301/304 stainless steel, ensuring long-term resistance to corrosive industrial fluids, lubricating oils, and moisture.

Applications

The 330104-00-10-20-02-05 3300 XL 8 mm Proximity Probes are primarily utilized for the continuous monitoring of radial vibration in high-speed rotating machinery. By providing a clear 200 mV/mil (7.87 V/mm) output, this probe captures the minute dynamic displacements of shafts within fluid-film bearings. This application is critical for detecting imbalance, misalignment, or bearing instability in steam turbines and centrifugal compressors, allowing for automated alarms and emergency shutdowns before mechanical failure occurs.

In the power generation and petrochemical sectors, this 3300 XL 8 mm Proximity Probes model is essential for axial (thrust) position monitoring. The 100 mm case length and 2.0-meter total cable length facilitate mounting through thick machine casings to track the longitudinal float of the shaft. This ensures that the rotating components maintain safe clearances from stationary parts, protecting thrust bearings in massive hydro-turbines and gas compressors from excessive wear and potential catastrophic contact.

The 330104-00-10-20-02-05 serves as a vital tool for Keyphasor reference and rotational speed measurement. By sensing a notch or keyway on the shaft, the probe generates a once-per-revolution pulse essential for phase angle measurement and diagnostic balancing. Its high-frequency response and resistance to voltage fluctuations make it suitable for integration into electronic overspeed protection systems, providing reliable data for transient analysis during machine startup and shutdown phases.

Specifications

Competitive Advantage

1. Comprehensive Global Certifications and Safety Compliance

The 330104-00-10-20-02-05 carries multiple international hazardous area approvals, including CSA, ATEX, and IECEx. This makes the probe a "global" solution, ready for immediate deployment in Zone 0, 1, and 2 environments where explosive gases or dust may be present. This extensive certification reduces compliance costs for international projects and ensures the highest level of safety for personnel and equipment in high-risk sectors like oil, gas, and mining.

2. Military-Grade Material Durability and Resilience

Featuring a probe tip made of Polyphenylene Sulfide (PPS) and a housing of AISI 303/304 stainless steel, this sensor offers military-grade resistance to chemical corrosion and thermal stress. The 3300 XL series design ensures that the probe maintains its structural integrity and measurement accuracy across an ultra-wide temperature range from -56°C to +109°C. This durability significantly lowers the Total Cost of Ownership (TCO) by extending the mean time between failures (MTBF) in harsh outdoor or high-heat industrial settings.

3. Superior Signal Integrity and ClickLoc Connectivity

The patented ClickLoc coaxial connector system provides a secure, vibration-resistant electrical path that prevents signal "drift" or accidental disconnection—the most common causes of false alarms. With a supply sensitivity of less than 2 mV per volt change and stable 50 Ω output impedance, the 330104-00-10-20-02-05 delivers consistent, repeatable data. This precision is essential for sophisticated diagnostic tools like orbit plots and spectral analysis, enabling accurate fault identification.
