3. Product Structure and Working Principle
The 330905-00-09-05-02-05 is an extension cable used in an eddy current proximity measurement system.
A complete proximity monitoring system normally consists of a proximity probe, extension cable, signal converter, and monitoring module. The probe generates an electromagnetic field near the rotating shaft surface. When the shaft moves due to vibration or displacement, the distance between the probe tip and the shaft changes.
The electrical characteristics of the probe signal change according to the shaft movement. The extension cable transfers this high-frequency signal from the probe to the monitoring equipment while maintaining signal stability and accuracy.
The cable assembly is specially designed to minimize signal degradation over long distances. This allows monitoring systems to accurately detect changes in machine operating conditions and provide reliable protection information.
