Overview

The 3300 XL 8 mm Proximity Transducer System includes:

• A 3300 XL 8 mm probe,
• A 3300 XL extension cable,
• A 3300 XL Proximitor Sensor.

This system delivers an output voltage that is directly proportional to the distance between the probe tip and the conductive surface being monitored. It is designed to measure both static (position) and dynamic (vibration) values. The 3300 XL system is primarily used for vibration and position measurements in fluid-film bearing machinery and is suitable for applications such as Keyphasor reference and speed measurements.
