330101-00-59-15-02-CN Bently Nevada 5.9in Case Probe

Product Overview

The Bently Nevada 330101-00-59-15-02-CN is a premier 3300 XL 8 mm Proximity Probe, a core component of the world’s most widely used eddy current sensor system. Featuring a 3/8-24 UNF thread and a standard cable design without armor, this probe is optimized for vibration and position monitoring of rotating machinery. The 3300 XL series offers improved performance over previous generations, providing a highly stable signal and a linear range of 2.0 mm (80 mils). This specific configuration is manufactured to meet country-specific agency approvals (-CN), ensuring compliance with local industrial standards.

Technical Specifications

Mechanical Design & Operational Benefits

1. Fully Threaded 5.9-inch Case: This probe configuration features a 5.9-inch overall case length with no unthreaded portion. This design allows for deep penetration into machinery housings and maximum adjustability along the 3/8-24 UNF threads to achieve the correct gap setting. Despite its length, the probe is robustly constructed, weighing in at 0.250 kg.

2. ClickLoc Connection System: The 330101-00-59-15-02-CN utilizes the gold-plated ClickLoc miniature coaxial connector. This connector system is designed to provide a secure, vibration-proof electrical connection between the probe and extension cable, preventing the signal "noise" and intermittent contact issues often found in inferior sensors.

3. Industry-Standard Durability: The probe tip is molded from high-performance Polyphenylene sulfide (PPS), providing a hermetic seal against oil, water, and other contaminants. Combined with a 304 stainless steel case, this probe is built to withstand the rigorous environment of steam turbines, pumps, and fans.

Installation Guidelines

Gap Setting: For standard applications using a 3300 XL Proximitor Sensor, the recommended gap is typically set to 1.27 mm (50 mils) to place the probe in the center of its linear range. The system provides a scale factor of 7.87 V/mm (200 mV/mil).

Mounting Torque: For the 3/8-24 UNF probe case, do not exceed the recommended installation torque of 11.3 N•m (100 in•lb). Over-tightening can stress the sensor housing and impact the electrical calibration.

Environmental Considerations: While the operating range is rated for -30°C to 70°C, ensure that the cable is routed with a minimum bend radius of 25.4 mm (1.0 in) to protect the internal FEP insulation from stress-cracking.

Technical FAQs

Q: Can this 3300 XL probe be used with older 7200 series Proximitor Sensors?
A: While the 3300 XL is backward compatible with some legacy systems, it is highly recommended to use it with the 3300 XL Proximitor Sensor for maximum accuracy and frequency response.

Q: What does the -CN approval option mean?
A: The "-CN" suffix indicates that the probe carries approvals and documentation specifically tailored for the China market, often including localized safety and hazardous area certifications.

Q: Is this probe suitable for high-vibration environments?
A: Yes, with a shock resistance rating of 40 g and the ClickLoc connector, the 330101 series is designed specifically for high-vibration industrial rotating machinery.
