Product Detailed Description
A complete 3300 XL 8 mm proximity transducer system consists of three main parts:
330180 XL 8 mm Probe: The sensor itself, which uses the eddy current principle to measure the distance between the probe tip and the observed surface (typically the shaft).
330101 or 330102 Extension Cable: A shielded cable that connects the probe to the proximity sensor. The "90" in the part number likely relates to the length of this cable in inches (90 inches = 2.286 meters).
3300 System Proximitor Sensor: The electronic module that excites the probe, processes the signal from the probe and extension cable, and provides an output voltage proportional to the gap (distance) between the probe tip and the target surface. The "-00" in the part number likely indicates a specific output and mounting configuration of the proximitor.
The system provides a linear output voltage proportional to the gap, which can then be used to determine vibration amplitude and phase, as well as shaft axial position or radial position.
