Product Introduction
The 330930-040-03-05 functions as the signal transmission path between the proximity probe and the Proximitor sensor.
The proximity probe measures the distance between its sensing tip and the rotating shaft using eddy current technology. Variations in shaft position alter the electromagnetic field generated by the probe, producing electrical signals proportional to shaft movement.
The extension cable transfers these low-level analog signals while maintaining their accuracy and minimizing electrical losses. High-quality shielding protects the signals from external electromagnetic noise, ensuring that the monitoring system receives reliable data for vibration analysis and machinery protection.
Although the cable itself does not generate measurement data, it plays an essential role in preserving the performance and accuracy of the complete proximity transducer system.
