Product Introduction
The 330180-X1-05 167066-01 is a 3300 XL 8 mm Proximity Probe System component from Bently Nevada. This part number specifically represents the Proximitor® Sensor (also known as the proximitor or driver) used in the 3300 XL series eddy current proximity probe system. It is a key component that provides radio frequency (RF) excitation to the probe, demodulates the signal, and outputs a linear voltage proportional to the distance between the probe tip and the target surface. The Proximitor sensor is designed for high reliability and stability in demanding industrial environments, serving as the interface between the probe assembly and the monitoring system.
