3300 XL 11mm Probe Installation Guide
Product Introduction
The Bently Nevada 330708-00-10-50-01-05 is a 3300 XL 11mm proximity probe system. This sensor measures radial vibration and axial position in critical turbomachinery. We commonly deploy it with the 3500 monitoring system. The probe delivers precise data for shaft relative vibration measurements. Its rugged construction suits harsh industrial environments. This specific model includes a FluidLoc cable for superior fluid resistance. The 5.0-meter integral cable offers versatile routing options.
Core Value
This probe delivers stable, repeatable measurements that protect your assets. Its primary strength lies in the proven 3300 XL platform accuracy. The 304 stainless steel case and PPS probe tip resist chemical corrosion. This composition ensures a long operational lifespan. The FluidLoc cable option prevents fluid ingress. This feature preserves signal integrity. Therefore, you minimize unplanned downtime. Moreover, the probe interfaces directly with Bently Nevada monitoring systems. This direct connection simplifies system integration. Most importantly, it provides essential data for predictive maintenance programs.
Technical Insights
This proximity probe operates on the eddy current principle. The Bently Nevada 330708-00-10-50-01-05 measures displacement against a conductive target. The system requires a specific proximitor and extension cable. The total system length must precisely match the factory calibration. The probe tip diameter measures 11mm. It offers a linear measurement range ideal for journal bearing monitoring. Specifically, the operating temperature spans -51°C to +177°C. The DC resistance is 5.9Ω ±0.5Ω. Meanwhile, the thread size is 5/8-18 UNF. The case length is 1.0 inch (code 10). This physical specification fits standard turbine casings.
Installation & Maintenance
Proper installation ensures maximum performance from the 330708-00-10-50-01-05. Firstly, inspect the probe tip for any physical damage. Then, thoroughly clean the mounting surface. Apply anti-seize compound to the threads when needed. Hand-tighten the probe until it contacts the shaft surface. Subsequently, use a torque wrench for final tightening. The recommended installation torque is 15.2 N·m. Do not exceed the maximum torque of 45.2 N·m. The connector requires only hand tightening. Furthermore, verify the gap voltage after installation. The monitor should read the appropriate DC voltage for your specified air gap. For routine maintenance, periodically inspect the cable for wear or chemical damage. Finally, always use the recommended extension cable and driver.
