Produkteinführung
The Bently Nevada 24765-02-01 Case Expansion Transducer Assembly is a high-precision sensor engineered to monitor thermal and mechanical expansion von machinery casings. It is designed to detect very small relative movements between the stationary casing and rotating components, providing essential data for vibration monitoring and predictive maintenance. Utilizing Linear Variable Differential Transformer (LVDT) technology, it delivers highly accurate displacement readings under industrial conditions, ensuring machinery safety and operational efficiency.
This assembly is widely applied in turbines, compressors, generators, and other rotating machinery, enabling condition-based monitoring and helping prevent rotor-stator contact, misalignment, or other mechanical failures caused by casing expansion.
