The Bently Nevada 330104-00-20-10-01-CN is a 3300 XL 8mm proximity probe featuring a 2.0-inch case and a 1.0-meter 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 330104-00-20-10-01-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 330104-00-20-10-01-CN maximizes machinery uptime by maintaining measurement integrity in extreme industrial environments. The probe tip utilizes a polyphenylene sulfide (PPS) construction that resists chemical corrosion and moisture ingress, preventing signal degradation in harsh conditions. The “CN” approval qualifies this unit for use in hazardous areas within China, ensuring full regulatory compliance for global operations. By adhering to API 670 standards, this probe ensures accurate monitoring for:
Maintenance technicians utilize the 1/2-20 UNF threads to secure the 330104-00-20-10-01-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 (01 option) provides a finger-tight locking mechanism that prevents signal interruption due to high-frequency machine vibration. 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.
