食品金属探测器应用电磁感原理来探测金属。所有金属包括铁和非铁都有很高的探测灵敏度。铁磁类金属进入探测区域将影响探测区域的磁力线分布，进而影响了固定范围的磁通。非铁磁类金属进入探测区域将产生涡流效应，也会使探测区域的 磁场分布发生变化。引发探测器发出鸣声。探测器的精确性和可靠性取决于电磁发射器频率的稳定性，一般使用从80 to 800 kHz的工作频率。工作频率越低，对铁的检测性能越好；工作频率越高，对高碳钢的检测性能越好。检测器的灵敏度随着检测范围的增大而降低，感应信号大小取决于金属粒子尺寸和导电性能。

The food metal detector uses the electromagnetic sense principle to detect metal. All metals, including iron and non iron, have high detection sensitivity. The entry of ferromagnetic metal to the detection area will affect the distribution of magnetic force lines in the detection region, and then affect the magnetic flux in the fixed range. The entry of non ferromagnetic metals in the detection region will produce eddy current effects, and will also change the distribution of magnetic fields in the detection region. Triggering the detector to make a sound. The accuracy and reliability of the detector depends on the frequency stability of the electromagnetic launcher, generally using the operating frequency from 80 to 800 kHz. The lower the working frequency, the better the testing performance of iron, the higher the working frequency, the better the detection performance of high carbon steel. The sensitivity of the detector decreases with the increase of the detection range, and the size and conductivity of the metal particles are determined by the size of the induction signal.
