- 3300 XL 8 mm Reverse Mount Probes
- 330105-02-12 3/8-24 UNF threads
- 3300 XL 8 mm Proximity Transducer System
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
The 3300 XL probe, extension cable, and Proximitor sensor have corrosion-resistant, gold-plated ClickLoc connectors. These connectors require only finger-tight torque (the connectors will "click" when tight), and the specially-engineered locking mechanism prevents the connectors from loosening. These connectors require no special tools for installation or removal.
The 330105-02-12-10-02-05 Bently Nevada 3300 XL 8 mm Reverse Mount Probes may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable4 with other nonXL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.
Internal Bearing Monitoring
In many high-speed turbines and compressors, critical measurement points are located deep within the internal bearing housing.
Problem: Standard probes cannot be screwed in from the outside due to excessive distance to the shaft or obstructions.
Solution: Install the probe in reverse, screwing it into the machine's internal bearing housing from the inside out.
Application: This is common in centrifugal gas compressors and steam turbines, where the probe must be mounted directly on a precision-machined bracket inside the machine to monitor radial vibration or axial thrust location.
