Bently Nevada 330103-00-20-10-02-00 3300 XL 8 mm Proximity Probe

Overview

This Bently Nevada 330103-00-20-10-02-00 is a 3300 XL 8 mm Proximity Probe designed for precise shaft vibration and position measurement in rotating machinery. Built with a Polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case, it offers durability in harsh industrial environments. The probe features an M10 x 1 thread, unthreaded length of 100 mm, overall case length of 200 mm, and a total length of 1.0 meter (3.3 feet). It comes with a miniature coaxial ClickLoc connector and standard cable. The probe is suitable for applications requiring reliable proximity sensing.

Technical Specifications Breakdown

Key parameters for the 330103-00-20-10-02-00 are listed below for quick reference:

Industry Applications

This proximity probe is commonly used for radial vibration and thrust position monitoring in turbines, compressors, pumps, and motors. Its 2 mm linear range and -9 Vdc recommended gap setting make it suitable for precise clearance measurements. The probe's temperature range supports use in high-heat environments like steam turbines or gas compressors. The ClickLoc connector simplifies field installation and reduces signal noise.

Installation & Setup Guidance

When installing the 330103-00-20-10-02-00, ensure the probe tip is clean and the target surface is smooth. Use the recommended field wiring: 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Maximum cable length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). For radial vibration, set the gap to approximately -9 Vdc (1.27 mm or 50 mils). Refer to frequency response graphs for signal rolloff at high frequencies with longer cables.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially in high-vibration or high-temperature areas. The probe is designed to seal differential pressure with a Viton O-ring, but it is not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe withstands 93% humidity per IEC 68-2-3 with less than 3% change in Average Scale Factor.

Compatibility & Integration

This probe is part of the Bently Nevada 3300 XL series and works with compatible Proximitor Sensors and monitoring systems. For intrinsically safe installations, use approved zener barriers per drawing 141092 or galvanic isolators. For non-incendive circuits, follow drawing 140979. The probe supports Class I, Zone 0 and Zone 2 hazardous area classifications.

Selection Guide & Purchasing Advice

When selecting the 330103-00-20-10-02-00, verify your required thread size, cable length, and connector type. For custom pressure testing or extended temperature ranges, contact the manufacturer.
