The Bently Nevada 330101-00-50-20-02-CN is a 3300 XL 8mm proximity probe featuring a 5.0-inch case and 2.0-meter cable. It provides high-precision, non-contact vibration and position sensing for critical machinery protection, certified for China Ex hazardous environments.
The Bently Nevada 330101-00-50-20-02-CN drives advanced predictive maintenance (PdM) by delivering high-fidelity vibration and position data. This 3300 XL series eddy current sensor tracks microscopic shaft movements without physical contact, ensuring zero mechanical wear and long-term signal stability. By integrating this probe into your Turbine Supervisory Instrumentation (TSI), you gain real-time diagnostics of radial vibration and axial thrust position. The sensor provides the critical raw data necessary for the 3500 Monitoring System to execute automated emergency trips and protect high-capital rotating assets.
This proximity probe excels in demanding environments like power stations, oil refineries, and chemical processing plants. The sensor employs a polyphenylene sulfide (PPS) tip that resists chemical degradation and moisture ingress, maintaining measurement integrity in harsh conditions. Furthermore, the 3300 XL series offers superior temperature stability and interchangeability compared to previous sensor generations. By adhering to API 670 standards, this probe ensures accurate monitoring for:
Technicians install the 330101-00-50-20-02-CN using its 3/8-24 UNF forward-mount threads to achieve the correct gap voltage—typically set at -10.0 Vdc. To complete a standard 5.0-meter or 9.0-meter measurement loop, the user must pair this 2.0-meter probe lead with the corresponding 3.0-meter or 7.0-meter 3300 XL extension cable. The included connector protector (02 option) seals the coaxial link against lubricating oils and environmental debris, which effectively eliminates signal interference and ground loops. This robust installation strategy guarantees a clean, actionable data stream for sophisticated rotor dynamics analysis.
