Product Overview
The Bently Nevada 330709-000-030-50-02-00 3300 XL 11 mm Proximity Probe is a precision engineered, factory-sealed sensor designed for reliable vibration and position measurement in rotating machinery. As part of the established 3300 XL series, this probe offers a direct replacement for existing installations without system reconfiguration. The Bently Nevada 330709-000-030-50-02-00 features a M16x1.5 thread, 0 mm unthreaded length, 30 mm overall case length, and a 5.0 meter total cable length with a miniature coaxial ClickLoc connector.

Installation and Setup Guidance
Correct installation of the Bently Nevada 330709-000-030-50-02-00 3300 XL 11 mm Proximity Probe is critical for accurate readings. Use the recommended 21.1 N•m (187 in•lb) torque for the M16x1.5 probe case. The connector-to-connector torque should be finger tight, with a maximum of 0.565 N•m (5 in•lb). Observe the 25.4 mm (1.0 in) minimum bend radius for the cable to avoid internal damage. Mount the probe on a flat surface at least 30.5 mm in diameter and ensure the shaft target has a minimum diameter of 152 mm to meet cross-talk limitations. This probe operates only with the five meter Proximitor Sensor; do not use with other lengths.
Maintenance and Reliability
The Bently Nevada 330709-000-030-50-02-00 3300 XL 11 mm Proximity Probe requires minimal routine maintenance. Regularly inspect the cable and connector for wear. The PPS tip and 304 SST case provide robust environmental resistance. The temperature schedule indicates operation from -55°C to +232°C depending on temperature classification; however, avoid prolonged exposure below -34°C to prevent pressure seal failure. For extended service life, maintain the recommended torque values and protect the cable from sharp bends.
Selection Guide and Purchasing Advice
When replacing an existing probe, verify that your system requires the Bently Nevada 330709-000-030-50-02-00 configuration: M16x1.5 thread, 0 mm unthreaded length, 30 mm case length, 5.0 meter cable, ClickLoc connector, and no special approvals. This probe is designed for use with the five meter Proximitor Sensor only. For technical support or to confirm compatibility, contact UBEST Automation at ubest101.myshopify.com.
