Bently Nevada 330101-02-32-10-02-05 3300 XL 8 mm Probe, 3/8-24 UNF, without Armor

Product Overview

From a maintenance engineer's perspective, the Bently Nevada 330101-02-32-10-02-05 is a critical component for reliable vibration monitoring. This 3300 XL 8 mm probe, with 3/8-24 UNF thread and without armor, is designed to withstand harsh industrial environments. Its robust construction, featuring a patented TipLoc molding method and CableLoc design, ensures a secure bond between probe tip and body, with a pull strength of 330 N (75 lbf).

Technical Specifications Breakdown

Key parameters for the 330101-02-32-10-02-05 are listed below for quick reference:

Industry Applications

Its linear range of 2 mm (80 mils) and incremental scale factor of 7.87 V/mm (200 mV/mil) provide precise vibration data. The 330101-02-32-10-02-05 is particularly suited for applications requiring ATEX, CSA, or IECEx approvals, ensuring safe operation in hazardous areas. Maintenance engineers value its ability to deliver consistent performance even in high-temperature environments up to +177°C.

Installation & Setup Guidance

For optimal performance, mount the probe with the recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) for radial vibration. Ensure the probe tip is clean and free from debris. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable. Maximum field wiring length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance & Reliability

Regularly inspect the probe and cable for physical damage. The probe's design, with a robust stainless steel case and PPS tip, minimizes wear. The FluidLoc cable option can prevent oil leakage through the cable interior. For extended temperature range applications, ensure the probe tip does not exceed +218°C (+425°F) and the cable +260°C (+500°F). Periodic calibration checks are recommended to maintain accuracy.

Compatibility & Integration

It uses a miniature coaxial ClickLoc connector for reliable signal transmission. The probe's nominal DC resistance is 7.59 ± 0.50 ohms for 1.0 meter length. Extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. Ensure compatibility with your existing Proximitor sensor and monitor for optimal performance.
