4. Product Working Principle
The 330500-02-04 works as a signal-conditioning device inside an eddy current proximity monitoring 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, misalignment, or mechanical stress, the electromagnetic field changes according to the distance variation between the probe and shaft.
The electrical signal generated by this change is transmitted to the 330500-02-04 through an extension cable. Inside the module, the signal is amplified, filtered, compensated, and converted into a stable analog output signal.
The processed output is then supplied to machinery protection systems, vibration monitoring systems, PLC control systems, distributed control systems, and industrial automation platforms.
The non-contact measurement method eliminates physical contact between the sensor and rotating shaft, reducing mechanical wear and providing long-term measurement reliability.
