BENTLY NEVADA 330105-02-12-05-02-05 3300 XL 8 mm Reverse Mount Proximity Probe

Product Overview

The Bently Nevada 330105-02-12-05-02-05 is a 3300 XL 8 mm reverse-mount proximity probe designed for non-contact measurement of shaft displacement and vibration in rotating machinery. Using eddy-current sensing technology, it detects changes in the gap between the probe tip and a conductive target. It is designed for use with compatible extension cables and Proximitor sensors in machinery monitoring systems.

Important Notes

• This item is a proximity probe, not a complete measurement system.

• A compatible extension cable and Proximitor sensor are required for operation.

• The listed 0.5 m length refers to the probe's integral cable; confirm the total calibrated system length before selecting additional components.

• The 7.87 V/mm scale factor applies to the compatible complete transducer system, not to the probe as a standalone device.

• Verify connector type, mounting dimensions, cable length, hazardous-area approvals, and the full part number before ordering.
