Bently Nevada 330101-30-63-10-02-CN 3300 XL 8 mm Probe, 3/8-24 UNF Thread, without Armor

Product Overview

The Bently Nevada 330101-30-63-10-02-CN is a 3300 XL 8 mm probe with 3/8-24 UNF thread, designed without armor for direct installation in industrial machinery. This eddy-current probe provides precise vibration and position measurements critical for predictive maintenance and machine protection. The 3300 XL series incorporates patented TipLoc and CableLoc technologies, delivering a robust bond between probe tip and body, and 330 N (75 lbf) pull strength for secure cable attachment.

Technical Specifications Breakdown

Key parameters for the 330101-30-63-10-02-CN are listed below for quick reference:

Industry Applications

Its robust PPS tip and stainless steel case withstand high temperatures and vibration, making it suitable for continuous operation in power generation and oil & gas facilities. The 2 mm linear range provides accurate radial vibration and thrust position measurements, enabling early detection of bearing wear or rotor imbalance.

Installation & Setup Guidance

Mount the probe using the 3/8-24 UNF thread with a recommended torque of 11.2 N·m (100 in·lbf) for standard forward-mounted probes. For the first three threads, use 7.5 N·m (66 in·lbf). The recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm or 50 mils). Field wiring requires 0.2 to 1.5 mm² (16 to 24 AWG) shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the Proximitor Sensor and monitor. Ensure the probe tip is clean and free of debris before installation.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially at the connector and probe tip. The patented CableLoc design provides 330 N (75 lbf) pull strength to resist cable pull-out. The probe sealing material is a Viton® O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. For applications with high humidity, the probe shows less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures reliable signal transmission. The system provides an Incremental Scale Factor of 7.87 V/mm (200 mV/mil) ± 5% for standard 1 or 5 meter systems, with interchangeability error included. For extended temperature range systems, the ISF is ± 6.5%.

Selection Guide & Purchasing Advice

When selecting a probe, consider the required unthreaded length, overall case length, and total cable length. The 330101-30-63-10-02-CN offers a 3.0 inch unthreaded length, 6.3 inch case length, and 1.0 meter cable. For applications needing fluid blocking, consider the optional FluidLoc cable.
