The Bently Nevada 330703-000-050-10-02-05 is an 11 mm proximity probe from the 3300 XL series. It features a permanently attached 5-meter armored cable and delivers precise, non-contact measurement of shaft displacement, vibration, or position in rotating machinery. This probe must be used with a compatible 3300 XL 11 mm Proximitor® (e.g., 3300/11-XX-XX) to form a complete transducer system.
With its larger active tip diameter, the 11 mm probe provides an extended linear range compared to smaller probes. As a result, it is ideal for large turbomachinery such as steam turbines, generators, and centrifugal compressors. The probe’s robust construction ensures stable performance even under high-vibration or high-temperature conditions.

Typical Applications
This probe is commonly deployed in power generation, oil & gas, and heavy industrial facilities. It supports continuous monitoring of journal bearing clearance, rotor runout, and axial thrust position. Optional FluidLoc® cable variants prevent oil wicking in lubricated environments, while connector protectors enhance reliability in humid or corrosive settings.
