The main function of the food metal detector is to detect whether the food contains metal impurities. When the food passes through the metal detector, if the metal detector contains metal impurities, the metal detector will give an alarm, so that the food containing impurities can be eliminated to ensure food safety.
The detection principle and installation procedure of the metal detector: The metal detector consists of two parts, namely the detection coil and the automatic rejection device, in which the detection coil is the core part. After the coil is energized, a magnetic field is generated, and if a metal enters the magnetic field, it causes a change in the magnetic field, and thus a metal impurity is judged. After the metal is detected, the sensor activates the signal to drive the automatic rejection device, such as the flip plate, push rod, etc., to remove impurities.
When you need to pay attention, sometimes the food metal detector will issue a false alarm. At this time, you must first check whether the power line is troublesome. If so, please use the power blocking transformer to supply power to the food metal detector. Then check whether the flexibility and phase are in the initial position. If the flexibility is too high or the phase is changed, the product effect will increase, and then a false alarm will occur. Check to see if there is any frequency conversion equipment in operation near the metal detector. The frequency conversion equipment will cause great annoyance to the metal detector and will also give a false alarm. In addition, the detected non-metallic materials generally have a certain product effect, and the size of the product effect will directly affect the operation function of the metal detector
