1. Opening size and position: In general, in order to obtain consistent readings, the detection product should pass through the center of the metal detector opening. If the opening position is too large and the detection product is too far away from the machine wall, it will be difficult to perform effective detection. The larger the opening, the worse the sensitivity of the metal detector.
2. Packaging materials used for the product: Any excess metal substances will have an impact on the detection. If the packaging material of the product contains metal materials, it will undoubtedly affect the sensitivity of the detection equipment and may produce incorrect metal signals. Therefore, Haiman can provide aluminum foil metal detection equipment for this demand.
3. Product features: Due to certain special characteristics of the product, such as meat and poultry products with high moisture or salt content, they are prone to exhibit the same behavior as metals when passing through metal detection machines, which can easily cause the equipment to produce “incorrect” signals and affect recognition sensitivity.
4. Testing machine frequency: Because different products have different characteristics, metal detectors need to adjust the electromagnetic frequency according to the different product types, otherwise sensitive recognition errors may occur. For dry products such as snacks, metal detectors are more efficient at high frequencies, but for wet products such as meat and poultry, it is best to operate at lower frequencies!
5. Surrounding environment: Check if there is a strong magnetic field or large metal blocks around the metal detector, which can change the magnetic field around the metal detector and cause the device to work normally, resulting in recognition errors!
In addition to the above influencing factors, the sensitivity and accuracy of the metal detection equipment itself are also important factors. As a professional metal detection equipment manufacturer in China, FanchiTech has a variety of high-quality and high-precision metal detection equipment to provide. The products have higher sensitivity, more stable and reliable use, and can also customize exclusive equipment solutions for different industries!
