Bently Nevada 3300 XL 8mm Non-Contact Proximity Probe 330105-02-12-90-02-05

Brief Product Description

This industrial-grade eddy current probe measures dynamic shaft vibration and static rotor position. The hardware provides critical data to machine protection systems for asset preservation.

Product Overview

The Bently Nevada 330105-02-12-90-02-05 reverse mount probe tracks mechanical movement without physical contact. The device generates an active radio frequency field to detect target distance changes. Consequently, the sensor outputs a clean voltage signal directly proportional to the gap. This reliable measurement helps predictive maintenance teams evaluate machinery health before failures occur.

Because this hardware complies fully with the rigorous API 670 standard, it integrates seamlessly into global industrial safety systems. The modular design enables complete interchangeability among probes, extension cables, and Proximitor sensors. This flexibility eliminates time-consuming bench calibration and matches components instantly. Furthermore, backward compatibility allows operators to deploy this component with legacy 3300 series 5 mm and 8 mm systems.
