The Bently Nevada 121M6469-02 is a wireless triaxial vibration and temperature sensor from the Ranger Pro series. It provides continuous, real-time monitoring of rotating machinery, measuring vibration across three axes (X, Y, Z) and casing temperature. Designed for predictive maintenance, the sensor helps in the early detection of issues such as imbalance, misalignment, and bearing faults. It is suitable for use in industries such as power generation, oil and gas, and manufacturing.
