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

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

In order to provide product safety and factory pass rate, the detection accuracy of the equipment has accurate requirements, especially in the application of food, medicine, chemical, plastics and other industries, the sensitivity of the metal detector is extremely high, and the following conditions will cause the detection sensitivity of the equipment to be affected:

Metal detector

1, the current metal detector has a variety of detection methods, the use of digital dual-frequency, digital single-frequency, analog machine and other different detection methods, the corresponding detection sensitivity is also different;

2. The different size of the equipment detection port will also affect the sensitivity. The smaller the detection port, the higher the sensitivity. Similarly, the smaller the contact surface between the detection object and the detection probe, the higher the detection accuracy;

3, put aside the factors of the equipment itself, but also consider the characteristics of the object, because the product effect is an important factor affecting the sensitivity of the metal detector, such as packaging material, temperature, shape, water content, etc. will form a greater impact on the product effect, this situation should be adjusted according to different circumstances of the sensitivity;

4, in addition to equipment and product factors, but also pay attention to the use of the metal detector environment, if the environment around the metal, magnetic, vibration and other factors, will cause some interference to the detection of equipment, resulting in sensitive substandard situation, this is to be avoided;
