Product Overview
The Bently Nevada 330171-24-40-05-02-00 is a 3300 5 mm Proximity Probe designed for non-contact measurement of shaft vibration, radial displacement, axial position, Keyphasor® reference, and speed on fluid-film bearing rotating machinery. It is part of the 3300 5 mm Proximity Transducer System, which consists of:
-
330171 5 mm Proximity Probe
-
3300 XL Extension Cable
-
3300 XL Proximitor® Sensor
The complete transducer system provides an output voltage proportional to the distance between the probe tip and the conductive target, enabling accurate static and dynamic measurements.
