The Bently Nevada 330103-02-12-10-02-00 is a high-precision eddy current sensor designed for the 3300 XL 8mm Proximity Transducer System. This probe measures static and dynamic distances between the probe tip and a target conductive surface. It provides critical data for vibration monitoring and position measurement in rotating machinery. As a fundamental part of the 3500 series machinery protection framework, it ensures the mechanical integrity of high-speed assets by detecting microscopic shaft movements.
Technical Configuration and Performance
This specific model features a customized hardware configuration to meet diverse industrial mounting and signal requirements. The 3300 XL 8mm system offers a linear range of 2.0 mm (80 mils) and maintains a stable scale factor across wide temperature fluctuations.
- Probe Tip Diameter: 8 mm
- Thread Size: 3/8-24 UNF (unthreaded length and overall length determined by option codes)
- Frequency Response: 0 Hz to 10 kHz
- Measurement Accuracy: Approximately ±1.5% in standard applications
- Operating Temperature: -35°C to +177°C (-31°F to +351°F)
- Total Length: 1.0 meter (standard probe lead)
- Connector Type: Miniature coaxial ClickLoc connector with gold plating
Durability and Environmental Resilience
Bently Nevada builds these probes to withstand the aggressive environments found inside machine cases. The probe tip consists of high-performance Polyphenylene Sulfide (PPS), which resists oil, water, and chemical degradation. Furthermore, the stainless steel probe body provides the necessary rigidity for stable mounting in high-vibration areas. The proprietary ClickLoc connectors ensure a moisture-resistant seal and prevent the cable from loosening during operation.
Installation and System Compatibility
For optimal performance, this probe must be paired with a 3300 XL extension cable and a 3300 XL Proximitor Sensor. The system total length (typically 5 or 9 meters) must match the Proximitor calibration to maintain the correct scale factor. Proper gapping is essential during installation to ensure the target remains within the linear range of the sensor. This modular approach allows for easy replacement of individual components without needing to replace the entire transducer string.
