Product Introduction
The Bently Nevada 330103-00-05-05-02-05 3300 XL 8 mm Proximity Probe is a precision vibration and displacement sensor designed for critical rotating machinery monitoring. Part of the renowned 3300 XL proximity transducer family, this probe uses eddy-current technology to provide non-contact, highly accurate measurements of shaft movement.
Its compact 8 mm probe tip allows installation in tight machinery spaces, while robust construction ensures long-term reliability even under high vibration, temperature, and industrial environmental stresses. This model is widely used in machinery protection systems to detect early signs of imbalance, misalignment, and bearing degradation, helping reduce unplanned downtime and maintenance costs.
