The Bently Nevada model 330101-00-85-05-01-05 is an 8 mm eddy-current proximity probe from the 3300 XL series. It features a permanently attached 8.5-meter FluidLoc® cable and an M10 × 1.0 mounting thread. This probe measures relative shaft displacement in rotating machinery with high accuracy and stability.
It must be used 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 output of 7.87 V/mm (200 mV/mil) over a linear range of 2.0 mm (80 mils).

Typical Applications
This probe is ideal for turbines, compressors, pumps, and motors where long cable runs are required. The 8.5-meter FluidLoc® cable eliminates the need for extension cables in many installations, reducing connection points and potential failure modes. Its robust design ensures reliable performance in oil-lubricated or humid environments.
Because of its noise immunity and compact size, the probe integrates easily into DIN-rail or panel-mounted monitoring systems. It supports both machinery protection and condition monitoring strategies per API 670 guidelines.
