1、 Function of metal detector: at present, metal detector is mainly used to detect food industry, pharmaceutical industry, chemical industry and health care products industry. The main function is to detect and eliminate the metal impurities mixed in the products during the production process. Once the metal impurities enter the magnetic field area, the metal detector can detect the existence of metal impurities and generate an alarm signal. The system will automatically eliminate the metal impurities according to the alarm signal, so as to improve the product quality, improve the production efficiency and protect the enterprise brand and consumers.
2、 Advantages of using metal detector: improving product quality; Strengthen the control of production process and raw material source; Optimize production links and improve production efficiency; Protect important production equipment to avoid unnecessary shutdown; Avoid consumer complaints and product recovery, and improve the corporate image; Strengthen the ability of production process control and quality control; Comply with national laws and industrial standards.
3、 Advantages of metal detector: it has 200 kinds of product storage functions and can quickly change product parameters; Greatly protect product quality and reduce downtime; The detection head is not easy to accumulate dust. The stable stainless steel detection head ensures the detection stability and long service life of the machine; It can be customized according to different product requirements of customers to meet the needs of different industries; The protection grade reaches IP65 and complies with HACCP and ifs certification.
4、 Working principle of metal detector: metal detector is generally composed of two parts, namely detection head and automatic removal device. The detection head is composed of three groups of induction coils, including the middle radiation coil and the same receiving coil on both sides. The oscillator connected by the middle radiation coil generates a high-frequency AC magnetic field, and the receiving coils on both sides are connected to make their induced voltages cancel each other before the magnetic field is disturbed. When the product containing metal foreign matters enters the detection range of the detection head, it will interfere with the magnetic field, resulting in the induced voltage of the receiving coils on both sides can not offset each other. The induced voltage without offset is processed by the sensor through the control system and generates a rejection signal, which is transmitted to the automatic rejection device.
