Description

The Bently Nevada 330101-20-45-05-02-05 3300 XL 8 mm Proximity Probe is a high-performance eddy-current transducer designed for non-contact measurement of shaft vibration and axial displacement in rotating machinery.It generates a high-frequency electromagnetic field at the probe tip, which is modulated by the proximity of a conductive target surface. These variations are transmitted via a shielded coaxial cable to a matched proximitor system, producing a calibrated voltage output proportional to displacement.The 330101-20-45-05-02-05 configuration defines cable length, connector style, probe tip design, mounting compatibility, and calibration variant. It is widely deployed in turbines, compressors, motors, and generators for critical machinery protection and predictive maintenance applications.
