The 3300 XL 8 mm Proximity Sensor System consists of the following components:
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor* sensor
The output voltage provided by the system is proportional to the distance between the probe tip and the observed point. This output voltage measures both static (position) and dynamic (vibration) values, with the distance between the probe tip and the observed conductive surface being the key measurement. The system is primarily used for vibration and position measurements in fluid film bearing machines, as well as for Keyphasor* reference and speed measurements.

The 3300 XL 8 mm system provides the most advanced performance in eddy current proximity sensor systems. The standard 3300 XL 8 mm 5-meter system fully complies with the American Petroleum Institute (API) 670 Standard (4th Edition), covering mechanical configuration, linear range, accuracy, and temperature stability.

All 3300 XL 8 mm proximity sensor systems offer this level of performance and support full interchangeability of probes, extension cables, and Proximitor sensors without the need to match or bench-calibrate individual components. Each 3300 XL 8 mm sensor system component is backward compatible and can be interchanged with other non-XL 3300 series 5 mm and 8 mm sensor system components. This compatibility extends to the 3300 5 mm probes for applications where 8 mm probes may be too large to meet existing installation space requirements.
