What is the reason why the sensitivity of food metal detector is not up to standard?


In order to detect metal impurities more accurately, the current metal detector equipment has a high sensitivity, but some users have incorrect sensitivity in the use process. What is the reason why the sensitivity of the metal detector is not up to standard in the use process?


In order to provide the product safety and ex factory qualification rate, there are accurate requirements for the detection accuracy of the equipment, especially in the application of food, medicine, chemical industry, plastic and other industries, the requirements for the sensitivity of metal detector are extremely high, and the following conditions will cause the equipment detection sensitivity to be affected:

1. At present, there are many detection methods for metal detector, such as digital dual frequency, digital single frequency, analog machine and so on;

2. Similarly, the smaller the contact surface between the detection object and the detection probe, the higher the detection accuracy;

3. In addition to the factors of the equipment itself, the characteristics of the tested object should be considered, because the product effect is an important factor affecting the sensitivity of the metal detector, such as packaging material, temperature, shape, water content, etc., which will have a greater impact on the product effect. In this case, the sensitivity should be adjusted according to different situations;

4. In addition to equipment and product factors, attention should also be paid to the use environment of metal detectors. If there are metal, magnetic, vibration and other factors around the environment, it will cause certain interference to the detection of the equipment, resulting in the situation that the sensitivity is not up to standard, which needs to be avoided;
