Bently Nevada 330104-01-05-50-02-00 3300 XL 8 mm Proximity Probe

Product Overview

When reliable vibration monitoring is critical for rotating machinery, the Bently Nevada 330104-01-05-50-02-00 3300 XL 8 mm Proximity Probe delivers precise measurements. This probe is part of the 3300 XL series, designed for non-contact displacement and position sensing in harsh industrial environments. With an M10 x 1 threaded design and integral armor, it withstands demanding conditions while maintaining accuracy.

Technical Specifications

The 330104-01-05-50-02-00 features an unthreaded length of 01 mm and an overall case length of 50 mm. Its total length is 5.0 meters (16.4 feet), terminated with a miniature coaxial ClickLoc connector and standard cable. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel. Nominal probe DC resistance is 8.73 ± 0.50 ohms for the 5.0 meter length. The probe is designed to seal differential pressure between tip and case using a Viton O-ring.

Industry Applications

This proximity probe is essential for monitoring shaft vibration and position in turbines, compressors, pumps, and motors. In power generation, it helps detect early signs of bearing wear or imbalance, preventing costly unplanned downtime. For oil and gas applications, its robust stainless steel case and sealed design resist corrosive atmospheres, ensuring long-term reliability.

Installation & Setup Guidance

Proper installation is key to accurate readings. Mount the probe with the M10 x 1 thread into a compatible bracket or housing, ensuring the tip is gapped at 1.27 mm (50 mils) from the target. Use only 3300 XL 8 mm extension cables and Proximitor sensors to maintain system accuracy. Connect the miniature coaxial ClickLoc connector securely, and verify power supply between -17.5 Vdc and -26 Vdc.

Maintenance & Reliability

Regular inspection of the probe tip and cable for physical damage is recommended. The PPS tip resists wear, and the stainless steel case provides corrosion resistance. Ensure the Viton O-ring remains intact to maintain pressure sealing. Periodic calibration checks against an AISI 4140 steel target help preserve measurement accuracy.

Compatibility & Integration

This probe integrates seamlessly with 3300 XL Proximitor sensors and extension cables. It is designed for use with Bently Nevada monitoring systems that accept 3300-series 5 mm or 8 mm probes. For optimal performance, use only 3300 XL 8 mm components in the measurement chain.

Selection Guide & Purchasing Advice

Before purchasing, verify that your system requires an 8 mm probe with M10 x 1 thread and 5.0 meter cable. Confirm the connector type (miniature coaxial ClickLoc) matches your extension cable.
