4. Product Function and Working Principle
The 330930-040-00-00 extension cable works together with a proximity probe and monitoring system to transmit displacement signals generated by the eddy current measurement principle.
During operation, the proximity probe detects the distance between the probe tip and the rotating shaft surface. Changes in shaft position caused by vibration, axial movement, or mechanical displacement are converted into electrical signals. The extension cable transfers these signals with minimal distortion to the monitoring module.
The cable plays an important role in maintaining measurement accuracy because signal quality directly affects vibration analysis results. A stable extension cable ensures that monitoring equipment can accurately detect abnormal operating conditions.
5. Main Applications
