Product Introduction
The Bently Nevada 330102-00-44-10-11-05 3300 XL 8mm Proximity Probe is a high-precision transducer designed for continuous vibration and position measurement in industrial rotating machinery. It forms a key part of Bently Nevada’s trusted 3300 XL series, engineered to deliver consistent performance under demanding operating conditions. The probe uses advanced eddy current technology to measure the distance between the probe tip and the target surface, typically a metal shaft or rotating component.
This model is optimized for use with 3300 XL Proximitor® sensors, ensuring accurate and stable readings even in environments with electrical noise, high temperature, and mechanical stress. The 330102-00-44-10-11-05 is widely recognized for its exceptional reliability, linearity, and interchangeability with other 3300 XL series components, making it suitable for both new installations and retrofit upgrades in condition monitoring systems.
