Overview

The 3300 XL 8 mm Proximity Transducer System includes:

• One 3300 XL 8 mm Probe
• One 3300 XL Extension Cable
• One 3300 XL Proximitor Sensor

This system measures the distance between the probe tip and a conductive surface, providing an output voltage directly proportional to that distance. It is capable of measuring both static (position) and dynamic (vibration) values. The 3300 XL system is primarily used for vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
