4. Product Working Principle

The 330500-02-CN operates as the electronic signal-conditioning unit in an eddy current proximity measurement system.

The connected proximity probe generates a high-frequency electromagnetic field near the rotating shaft surface. When the shaft moves due to vibration, imbalance, thermal expansion, mechanical loading, or alignment changes, the distance between the probe and the shaft changes.

This displacement variation modifies the electromagnetic field of the probe and creates an electrical signal corresponding to the shaft movement. The signal is transmitted through an extension cable to the 330500-02-CN module.

Inside the module, the received signal is processed through precision electronic circuits. The system performs signal amplification, filtering, compensation, and linear correction to ensure the output signal accurately represents actual shaft displacement.

The processed analog output can then be connected to machinery protection systems, vibration monitoring systems, PLC controllers, distributed control systems, and industrial automation platforms.

Because the measurement method does not require physical contact with the rotating shaft, mechanical wear is eliminated. This improves measurement stability, reduces maintenance requirements, and provides reliable long-term monitoring performance.
