The Bently Nevada 102550-01 is a precision eddy current sensor designed for the 3300 XL Proximity Transducer System. This probe provides high-accuracy, non-contact displacement measurements, allowing for real-time monitoring of shaft vibration and axial position in critical rotating machinery. Engineered with a hermetically sealed tip and a rugged stainless steel body, the 102550-01 is capable of operating in harsh industrial environments characterized by high-pressure steam, lubricating oils, and extreme temperatures. It serves as the primary sensing element that, when paired with an extension cable and Proximitor sensor, forms a complete diagnostic solution for machinery protection.
