4. Product Structure and Working Principle
The 330930-040-00-05 extension cable is designed to transfer the electrical signal generated by a proximity probe to the monitoring system.
The proximity probe operates based on eddy current measurement technology. When the rotating shaft moves closer to or farther away from the probe tip, the electromagnetic field changes. These changes are converted into electrical signals representing shaft displacement and vibration movement.
The extension cable provides a stable connection path between the probe and the monitoring equipment. Its shielding structure helps reduce electrical interference, allowing the monitoring system to receive cleaner and more accurate measurement signals.
In critical machinery applications, signal stability is essential because inaccurate transmission can affect vibration analysis, alarm settings, and equipment protection decisions.
