Introduction to Metal Alarm
Metal alarms, also known as metal detectors, are devices used to detect the presence of metal objects. They work based on the principle of electromagnetic induction. When a metal object enters the detection field of the metal alarm, it causes a change in the magnetic field, which triggers an alarm signal. Metal alarms are widely used in various industries such as security inspection at airports, railway stations, and public events; food and pharmaceutical industries to detect metal contaminants in products; and mining and archaeological fields to locate buried metal objects. In China, the metal alarm manufacturing industry has witnessed significant growth in recent years, with many companies offering high - quality and innovative products.
