Bently Nevada 330103-00-12-10-01-00 3300 XL 8mm Proximity Probes

The Bently Nevada 330103-00-12-10-01-00 — 3300 XL 8mm Proximity Probe is a precision-engineered eddy current sensor, part of the globally trusted 3300 XL series by Bently Nevada. Designed for continuous, accurate measurement of shaft position and vibration in rotating machinery, this proximity probe plays a vital role in protecting equipment and optimizing performance across critical industries.

This specific model features an 8 mm probe tip and a 1 meter cable, making it ideal for installations requiring longer reach between the probe and its associated Proximitor Sensor. Ruggedized to endure harsh industrial environments, the probe delivers reliable performance under high temperatures, in chemically aggressive areas, or even submerged conditions thanks to its IP68 rating.

When combined with the corresponding 3300 XL Proximitor Sensor and extension cable, this probe provides a linear output over a broad measurement range, enabling maintenance teams to track dynamic shaft movement in real time. Used worldwide in sectors such as oil & gas, power generation, and chemical processing, it is an essential component for protecting the health of vital rotating assets.
