V and 125 kHz. The metal debris passes via the sensor at diverse speeds, plus the experimental output is shown in Figure 14 (the short line indicates the typical deviation). We are able to see from the experimental final results that the more quickly the metal debris passes through the sensor, the higher the ML-SA1 Epigenetics voltage amplitude of the sensor output plus the larger the sensitivity in the sensor. five.6. Nonferrous Debris Detection Sensitivity The ability in the sensor to detect nonferrous magnetic metal debris was also verified. Copper debris with diameters of 500 and 800 were chosen for the experiments. Similarly, the excitation signal is 0 V and 125 kHz. The velocity from the copper debris passing by means of the sensor is fixed as 0.two m/s. The final output signals in the corresponding copper debris are shown in Figure 15. The experimental final results clearly indicate the output signal is in opposite phase for the ferrous particle signal. Consequently, the kind of particle could be identified by observing the signal phase. Assuming that the output signal amplitude is proportional towards the volume of the debris, it might be deduced that the detection limit on the sensor for nonferrous is 500 three 1360 313 (The noise level of the circuit is 400 mV, 400 as well as the output voltage is 1360 mV when a copper debris using a diameter of 500 passes by way of the sensor).Sensors 2021, 21,experiment and passed by means of the sensor with various spacing as well as the identical speed (0.2 m/s), as well as the output benefits are shown in Figure 13. The induced voltages of adjacent debris at different intervals are shown in Figure 13. From the experimental benefits, it is obvious that when the spacing is much less than 25 mm, the output voltage signals are 11 of 14 entirely superimposed with each other, and when the spacing is greater than 90 mm, the output voltage signals are fully separated.(a)(b)(c)(d)Sensors 2021, 21,12 of(e) (f) standard deviation).

We pick 200 m ferrous metal debris for the experiment. Similarly, the excitation signal is 0 V and 125 kHz. The metal debris passes via the sensor at distinctive speeds, as well as the experimental output is shown in Figure 14 (the quick line indicates theFigure 14.

Copper debris with diameters of 500 m and 800 m had been chosen for the experiments. Similarly, the excitation signal is 0 V and 125 kHz.
