The effectiveness of metal detection machines is influenced by multiple factors. In order to obtain accurate detection results, customized settings and adjustments need to be made based on specific production environments and product characteristics, and corresponding measures need to be taken to reduce interference and errors.
1, Metal material elements
Include the types of metal materials, the location and position of air pollutants in the inspected goods. The key types of metal materials are those that are both conductive and magnetic, such as iron and magnetizable stainless steel plates, which are all very easy to detect. The key to the specificity of air pollutants in metal materials is that it is difficult to detect when the conduction band magnetic metal material is parallel to the operating direction; It is very easy to verify the conductivity of metal materials when they are perpendicular to the operating direction.
2, Environmental factors
Interference signals from the switch power supply of detection equipment, vibrations from machinery and equipment, temperature changes, and changes in surrounding electromagnetic fields are all factors that can cause false alarms in detection equipment. Unless this problem is addressed through well-designed solutions, environmental factors such as these can only be handled by reducing sensitivity.
3, Inspect the elements of the product
Contains the types of products and their temperature. The product category refers to the composition of the salt and acidic components of the product, which immediately endangers the conductivity of the product. The more salt and acidic components there are, the stronger the conductivity and the greater the utility of the product. Relative testing is difficult and sensitivity is low; The higher the temperature, the stronger the autonomous movement of molecular structure and the stronger the conductivity from the perspective of organic chemistry. Relatively speaking, the inspection is a bit difficult. However, if we can reduce the output power of machinery and equipment, carry out product compensation, suppress product utility, and forget about the past, we can save this element of relativity.
4, Detecting the elements of the equipment itself
The elements of the detection equipment itself include mouth opening specifications, equipment frequency, operating speed, and transmission belt data signal size. The larger the opening size, the lower the sensitivity of the inspection, and the smaller the opening size, the higher the precision of the relative inspection. The higher the frequency of the equipment, the higher the relative sensitivity of the inspection.
