The Bently Nevada 330103-00-21-10-11-CN is a 3300 XL 8mm proximity probe featuring a 2.1-inch case and 1.0-meter fluid-resistant cable. Certified for China Ex hazardous areas, it delivers precision non-contact vibration monitoring for critical assets in temperatures up to +177°C.
The Bently Nevada 330103-00-21-10-11-CN drives high-performance machinery protection by capturing high-resolution vibration and displacement data. This 3300 XL series eddy current sensor monitors 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 enable real-time diagnostics of radial vibration and axial thrust position. The sensor delivers the critical raw data necessary for the 3500 Monitoring System to execute automated emergency trips, protecting high-capital rotating assets from catastrophic failure.
The 330103-00-21-10-11-CN maximizes machinery uptime by maintaining measurement integrity in extreme industrial environments. The fluid-resistant cable (11 option) provides an extra layer of protection against chemical degradation, shielding the signal path from lubricating oils and hydraulic fluids. Furthermore, the probe tip utilizes a polyphenylene sulfide (PPS) construction that resists moisture ingress. The “CN” approval qualifies this unit for use in hazardous areas within China, ensuring full regulatory compliance for:
Maintenance technicians utilize the 3/8-24 UNF threads to secure the 330103-00-21-10-11-CN into machine housings, typically gapping it at -10.0 Vdc for optimal linearity. To complete a standard 5.0-meter or 9.0-meter electrical loop, pair this 1.0-meter probe lead with the corresponding 3300 XL extension cable (4.0m or 8.0m). The gold-plated ClickLoc connector provides a secure, vibration-resistant link that prevents signal interruption. This robust electrical connection ensures that the 3500 rack receives a clean, noise-free data stream for advanced rotor dynamics analysis and automated machinery protection.
