Food and pharmaceutical metal detectors typically use a combination of electromagnetic and magnetic fields to detect metal contaminants in products. When a metal object passes through the detector, it disturbs these fields, which triggers an alarm or other signal to alert operators that there is a metal contaminant in the product.
Overall, food and pharmaceutical metal detectors are an important tool in ensuring the safety and quality of food and pharmaceutical products, and they play a critical role in helping to protect the health of consumers.
