3300 XL 8 mm Proximity Transducer System Overview

The 3300 XL 8 mm Proximity Transducer System includes the following components:

• One 3300 XL 8 mm probe
• One 3300 XL extension cable
• One 3300 XL Proximitor Sensor

This system provides an output voltage directly proportional to the distance between the probe tip and the observed conductive surface. It is capable of measuring both static (position) and dynamic (vibration) values. The system is primarily used for:

• Vibration and position measurements on fluid-film bearing machines
• Keyphasor reference and speed measurements

Specifications

Proximitor Sensor Input:

• Accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm Proximity Probe and Extension Cable.
