Product Overview
The Bently Nevada 330904-00-15-05-11-00 is a 3300 NSv proximity probe designed for reliable vibration and position monitoring in critical rotating machinery. This industrial automation module features an M8X1 threaded case with stainless steel armor, a 150 mm overall case length, and a 0.5 meter (20 inch) FluidLoc cable with a miniature coaxial ClickLoc connector. It offers enhanced chemical resistance over previous 3300 RAM probes, making it suitable for process compressor applications. The probe is supplied new and in original factory packing, backed by a 12-month warranty.

Industry Applications
The 330904-00-15-05-11-00 is engineered for use in turbomachinery, compressors, pumps, and other rotating equipment where precise shaft vibration and axial position monitoring are essential. Its enhanced chemical resistance makes it ideal for process compressor applications where exposure to aggressive media is common. The probe's superior side-view characteristics allow accurate gapping even in confined spaces.
In a typical replacement scenario, this probe directly replaces older 3300 RAM probes without mechanical or electrical modifications, minimizing downtime and upgrade costs.
Installation & Setup Guidance
Proper installation is critical for accurate measurements. Follow these guidelines:
- Mount the probe with the recommended torque: finger tight, maximum 0.56 N•m (5 in•lb).
- Ensure the probe tip is clean and free from debris before installation.
- Set the initial gap to 1.0 mm (40 mils) using a suitable shim or feeler gauge.
- Route the cable with a minimum bend radius of 25.4 mm (1.0 in) to avoid damage.
- For field wiring, use a three-conductor shielded triad cable with conductor sizes 0.2 to 1.5 mm² (16 to 24 AWG). Maximum cable length between the Proximitor and monitor is 305 meters (1,000 feet).
Maintenance & Reliability
Routine inspection of the probe and cable is recommended to ensure long-term reliability. Check for physical damage, cable wear, and connector integrity. The probe's stainless steel case and PPS tip offer excellent durability in harsh environments. Operating within the specified temperature range (-52°C to +177°C) ensures consistent performance. Regular calibration checks can help maintain measurement accuracy.
Compatibility & Integration
The 330904-00-15-05-11-00 is mechanically and electrically compatible with Bently Nevada's previous 3300 RAM proximity probe and extension cable systems. It works seamlessly with 3300 XL NSv Proximitor Sensors and standard Bently Nevada monitoring systems. The ClickLoc connector ensures a secure, reliable connection.
Selection Guide & Purchasing Advice
Before ordering, verify your specific requirements: unthreaded length (00 mm), overall case length (150 mm), total cable length (0.5 m), connector type (ClickLoc with FluidLoc cable), and agency approval (not required). Ensure the probe thread (M8X1) matches your mounting configuration. For assistance, contact the experts at PLC Source PRO to confirm compatibility and availability.
