The Bently Nevada 330106-05-30-15-02-05 3300 XL 8 mm Reverse Mount Probe is a high-precision proximity probe engineered for critical machinery monitoring in industrial environments. As part of the 3300 XL series, this probe is designed for applications requiring reverse mounting in restricted spaces, allowing flexible installation without compromising measurement accuracy.

The 8 mm probe tip provides precise radial displacement and vibration detection, making it suitable for high-speed rotating machinery such as turbines, compressors, generators, and pumps. Its robust construction ensures reliable operation in extreme temperatures, high vibration, and humid conditions. When paired with Bently Nevada 3300 XL monitoring systems, it enables predictive maintenance, early fault detection, and enhanced operational safety.

This probe is particularly suited for installations where longer reach is required, as its 1.5-meter total length allows it to monitor shaft movement while remaining securely mounted in confined or challenging locations.
