In order to more accurately detect metal impurities, current food metal detector equipment has high sensitivity. However, some users may experience sensitivity errors during the application process. What are the reasons why the sensitivity of food metal detectors does not meet the standard?

In order to ensure the safety and factory qualification rate of the supplied products, there are accurate requirements for the inspection accuracy of the equipment, especially in the applications of food, medicine, chemical, plastic and other industries. The sensitivity requirements for food metal detectors are extremely high, and the following situations may affect the inspection sensitivity of the equipment:

1. There are various inspection methods for food metal detectors currently available, including digital dual frequency, digital single frequency, and analog machines. The corresponding inspection sensitivity also varies;

2. The different sizes of inspection ports for food metal detectors can also affect sensitivity, with smaller inspection ports having higher sensitivity; Similarly, the smaller the contact surface between the inspection item and the inspection probe, the higher the inspection accuracy will be;

3. Apart from the components of the food metal detector itself, the characteristics of the test substance should also be considered. As the product effect is a critical component that affects the sensitivity of the food metal detector, factors such as packaging material, temperature, shape, and moisture content can have a significant impact on the product effect. In this case, the sensitivity should be adjusted according to different situations;

4. In addition to food metal detectors and product components, attention should also be paid to the application environment of food metal detectors. If there are metal, magnetic, vibration and other components in the surrounding environment, it will inevitably interfere with the inspection of the equipment, leading to situations where the sensitivity does not meet the standard. This needs to be avoided;
