The Bently Nevada 330103-00-11-10-12-00 is a precision-engineered eddy current proximity probe part of the 3300 XL 8 mm series. This sensor is designed for non-contacting displacement measurements in rotating machinery. By detecting the distance between the probe tip and a conductive target (such as a shaft), it facilitates the monitoring of radial vibration, axial thrust, and speed. The 3300 XL system is renowned for its linear range and signal stability, even when subject to significant temperature fluctuations in industrial environments.
