Bently Nevada 330101-00-80-10-02-00 3300 XL 8 mm Proximity Probe

Description

Engineered for high-precision rotating machinery monitoring, the Bently Nevada 330101-00-80-10-02-00 is an eddy-current 8 mm proximity probe designed for non-contact shaft vibration and position measurement. This exact configuration is built with a standard 3/8-24 UNF thread housing and is fully threaded (0.0 inches of unthreaded length), presenting an extended 8.0-inch overall case length. It integrates a 1.0-meter standard coaxial cable without armor, terminated in a miniature ClickLoc connector. Free of hazardous area approvals, this specific variant is optimized for cost-effective installation in general-purpose industrial environments where mechanical armor or connector protectors are not required.

As a key component of the 3300 XL 8 mm Proximity Transducer System, this probe operates on the eddy-current principle to measure static and dynamic distances between the probe tip and a conductive target, typically an AISI 4140 steel shaft. It pairs seamlessly with a 3300 XL Proximitor sensor and a corresponding extension cable, providing a linear range of 2.0 mm (80 mils) with an incremental scale factor of 7.87 V/mm (200 mV/mil). This system delivers highly accurate displacement readings that are essential for machinery protection and predictive maintenance systems, such as the Bently Nevada 3500 series rack.

Features

• Fully threaded case (0.0 in unthreaded length) and long 8.0 in overall housing, ideal for deep bearing housings.
• 1.0 meter (3.3 feet) standard unarmored coaxial cable configuration.
• Standard miniature coaxial ClickLoc connector provides low-profile connection to extension cables.
• High-performance eddy-current transducer technology delivers reliable non-contact measurement.
• Full compatibility with Bently Nevada 3300 XL monitoring systems and 3500 rack modules.
• Viton O-ring design provides high-resistance sealing against differential pressure.

Applications

• Steam and gas turbine radial shaft vibration monitoring.
• Compressor, expander, and pump shaft axial position and displacement measurement.
• Thrust bearing wear and rotor dynamic tracking in large rotating machinery.
• Permanent machinery protection installations on industrial bearing casings.

Installation Guidelines

To ensure optimal performance and prevent premature failure of the 3300 XL proximity probe during installation, observe the following guidelines:

• Probe Gap: Mount the probe with the appropriate mechanical clearance gap (typically calibrated to -9 Vdc, or approximately 1.27 mm / 50 mils) corresponding to the target center-line of the linear range.
• Thread Engagement: Do not exceed the maximum recommended thread engagement of 0.563 inches for 3/8-24 threads to prevent binding.
• Cable Routing: Always route the probe and extension cables with proper shielding, grounding, and isolation from high-voltage lines. Use conduits or cable trays to prevent mechanical damage.
• Torque Limits: Connectors should be finger-tight only. Do not use tools on the ClickLoc gold connectors to avoid damage to the gold plating and physical structure.
