Product Introduction
The Bently Nevada 330707-00-55-10-01-00 is a 3300 XL 11 mm Proximity Probe designed for precise vibration and position measurement in rotating machinery. This probe features a 5/8-18 UNF thread, an unthreaded length of 0.0 inches, and an overall case length of 5.5 inches. With a total length of 1.0 meter (3.3 feet), it uses a miniature coaxial ClickLoc connector with connector protector and standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 304 stainless steel (SST). This model is an excellent upgrade for older proximity probe systems, offering improved reliability and ease of installation.

Industry Applications
The Bently Nevada 330707-00-55-10-01-00 is ideal for monitoring shaft vibration and thrust position in turbines, compressors, pumps, and motors. In a typical steam turbine upgrade, this probe replaces older 3300 series sensors to provide more accurate radial vibration data. Its robust stainless steel case and PPS tip withstand harsh industrial environments, making it suitable for oil and gas, power generation, and petrochemical plants.
Installation & Setup Guidance
Install the 330707-00-55-10-01-00 by threading the probe into a mounting block with a 5/8-18 thread. Apply a recommended torque of 15.2 N·m (133 in·lb) to ensure a secure seal without damaging the housing. Use the finger-tight connector-to-connector torque (maximum 0.565 N·m) for the ClickLoc connector. Ensure a minimum bend radius of 25.4 mm (1.0 inch) for the cable to prevent signal degradation. For best performance, calibrate the probe gap to the target surface as specified in the system manual.
Maintenance & Reliability
Routine inspection of the Bently Nevada 330707-00-55-10-01-00 includes checking the probe cable for cuts or kinks and verifying that the connector is securely mated. The probe’s Viton O-ring seals withstand differential pressure, but avoid exposing the probe to temperatures below -34°C (-30°F) to prevent seal failure. Clean the probe tip with a soft cloth to remove debris. Regular maintenance extends the probe’s service life and reduces unplanned downtime.
Selection Guide & Purchasing Advice
When selecting the 330707-00-55-10-01-00, verify that your system requires a 5/8-18 UNF thread, a 1.0-meter cable, and miniature ClickLoc connector.
