Description
1. Product Overview
The Bently Nevada 330104-00-22-10-02-05 is a high-precision 3300 XL 8 mm Proximity Probe designed for industrial machinery condition monitoring. Part of Bently Nevada’s flagship transducer system line, it operates on the eddy-current principle to provide continuous, highly accurate measurements of shaft vibration, radial displacement, and axial position on fluid-film bearing machines such as steam turbines, compressors, pumps, and large motors.
2. Part Number Breakdown (330104-00-22-10-02-05)

4. System Matching & Installation Requirements
- System Compatibility: As a 1.0-meter probe model (
CC = 10), it must be paired with a 4.0-meter extension cable (such as the 330130-040 series) and a 3300 XL Proximitor Sensor calibrated for a 5.0-meter total system length. - Mechanical Torque & Mounting: Use the specified lock nut and maintain proper thread engagement (recommended torque limit typically sits near 11.2 N\cdotm / 100 in\cdotlbf for M10 configurations). Avoid over-tightening the entire 220 mm case length into shallow mounting ports.
- Routing & Bend Radius: The integrated stainless steel armor provides exceptional resistance against physical abrasion, pulling, and crushing. Ensure the cable is routed safely away from high-voltage lines, maintaining a bend radius no tighter than 25.4 mm (1.0 in).
