Bently Nevada 330101-00-61-20-02-05 3300 XL 8 mm Proximity Probe

Overview of System Capabilities

The Bently Nevada 330101-00-61-20-02-05 is a high-precision 3300 XL 8 mm proximity probe designed for non-contacting vibration and displacement measurements. This transducer system operates on the eddy current principle, which allows for the accurate monitoring of rotating shaft behavior in critical industrial machinery. Because it belongs to the 3300 XL series, it offers a standardized linear range of 2.0 mm (80 mils) and provides a highly stable signal output even in harsh operating environments. Moreover, this specific configuration is engineered to interface seamlessly with 3300 XL Proximitor Sensors to ensure comprehensive machine protection.

Enhanced Thermal and Environmental Resilience

One of the primary advantages of the 330101-00-61-20-02-05 model is its complete compatibility with Extended Temperature Range (ETR) environments. While standard probes often struggle under extreme heat, this ETR-compatible probe maintains structural and electrical integrity at temperatures reaching up to 218°C (425°F). Consequently, it is an ideal solution for monitoring turbines, compressors, and motors where ambient heat is a constant factor. Furthermore, the probe features the patented ClickLoc miniature coaxial connector, which provides a secure, vibration-resistant connection that prevents signal loss due to mechanical loosening.

Mechanical Configuration and Design

This probe features a 3/8-24 UNF threaded body, which facilitates straightforward installation into standard mounting brackets or machine housings. The 6.1-inch case length allows for deep penetration into machinery casings to reach the target shaft. Additionally, the assembly includes a 2.0-meter integrated cable. Although this version does not include stainless steel armor, its robust construction ensures durability against typical industrial fluid exposure. To ensure global compliance, the unit carries multiple hazardous area certifications, including ATEX, IECEx, and CSA approvals, making it suitable for use in explosive atmospheres.
