Product Overview
The Bently Nevada 330102-00-20-05-01-05 is a 3300 XL 8 mm Proximity Probe designed for precise vibration and position measurement in rotating machinery. This probe features a 3/8-24 UNF thread with armor, a 0.5 meter cable, and a miniature coaxial ClickLoc connector with connector protector. It is engineered for harsh industrial environments, offering a linear range of 2 mm (80 mils) and a recommended gap setting of -9 Vdc for radial vibration applications. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel, ensuring durability and corrosion resistance.

Industry Applications
Its robust design and agency approvals (CSA, ATEX, IECEx) make it suitable for hazardous areas, including oil and gas, petrochemical, and power generation facilities. The 2 mm linear range and -9 Vdc gap setting ensure accurate radial vibration measurement, helping prevent unplanned downtime.

Installation & Setup Guidance
When installing the 330102-00-20-05-01-05, ensure the probe tip is clean and the target surface is smooth. The maximum thread engagement length is 0.563 in. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring. The maximum field wiring length between the probe and monitor is 305 meters (1,000 feet). Refer to frequency response graphs for signal rolloff at high frequencies with longer cables. The probe is not pressure tested before shipment; contact Bently Nevada for pressure seal testing if required.
Maintenance & Reliability
Inspect the probe periodically for physical damage or contamination. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is designed for long-term reliability in harsh environments, with a PPS tip and stainless steel case resisting corrosion and wear.
Compatibility & Integration
This probe is part of the 3300 XL series and is compatible with Bently Nevada 3300 XL Proximitor sensors and monitors. It supports intrinsic safety when installed with approved zener barriers or galvanic isolators per drawing 141092, and non-incendive operation per drawing 140979.
Selection Guide & Purchasing Advice
When selecting a proximity probe, consider the required cable length, connector type, and agency approvals. The 330102-00-20-05-01-05 offers a 0.5 meter cable with a ClickLoc connector and CSA/ATEX/IECEx certifications.
