Perancangan Sistem Sensor Arus Eddy Berbasis Solenoid Untuk Pengukuran Jarak

---

This research discusses the design and implementation of an eddy current-based sensor system for distance measurement using excitation and detection solenoids. The system utilizes electromagnetic induction generated by changes in magnetic field in the excitation solenoid. Variations in solenoid size and material (aluminum and copper) were used to analyze their effect on the sensitivity and accuracy of the distance measurement system. The test results show that the sensor output voltage increases as the distance between the solenoid and the test material increases until it reaches saturation. Copper plates produce higher voltage than aluminum plates due to better electrical conductivity. This phenomenon is utilizing the concept of skin depth, which is the depth of penetration of the electromagnetic field into the material. This effect results in eddy currents that are more concentrated at the surface, resulting shallower in copper due to its higher conductivity, thus increasing the magnetic field intensity and induced voltage. The excitation frequency used was 1 MHz, with varied detection solenoid diameter (35.5 mm, 49.5 mm and 60.5 mm). The designed system shows good response and sensitivity, with potential applications in industries such as thickness measurement and material inspection.
