The Bently Nevada model 330101-00-20-90-02-05 is an 8 mm eddy-current proximity probe from the 3300 XL series. It integrates a permanently attached 2.0-meter FluidLoc® cable and features an M10 × 1.0 mounting thread. This probe accurately measures relative shaft displacement in rotating machinery under demanding industrial conditions.
It requires pairing with a compatible 3300 XL 8 mm Proximitor® (e.g., 3300/05-XX-XX) to form a complete transducer system. The probe delivers a standard sensitivity of 7.87 V/mm (200 mV/mil) across a linear range of 2.0 mm (80 mils).
Key mechanical enhancements include TipLoc® molded tip construction and CableLoc® strain relief. Together, they provide high resistance to vibration, thermal cycling, and cable pull forces—up to 330 N (75 lbf)—without compromising signal integrity.

Typical Applications
This probe is well suited for steam turbines, centrifugal compressors, gearboxes, and large motors. Its short 2.0 m cable is ideal for panel-mounted Proximitors located near the machine bearing housing. The ruggedized design ensures long-term stability in high-vibration or oil-splash environments.
Because it uses the standardized 3300 XL interface, it integrates seamlessly into existing Bently Nevada monitoring systems without requiring hardware changes.
