Factors affecting the metal detector machine

1, metal factors

It includes the type of metal and the direction and position of metal contaminants in the detected product. The type of metal is mainly divided into both electrically and magnetically conducting metals, such as iron and stainless steel with magnetic are easily detected. The directivity of metal pollutants is mainly that when the magnetic metal is parallel to the direction of operation, it is not easy to detect. When the conductive metal is perpendicular to the direction of operation, it is easy to detect.

2, environmental factors

The electromagnetic interference, equipment vibration, temperature change and magnetic field around the detector will cause the false alarm of the detection machine. If such environmental factors are solved, unless a good design plan is used to solve the problem, we can only solve the false alarm by reducing the sensitivity.

3, detection of product factors

It includes the type of product and the temperature of the product. Product type refers to the salt and acidic component content of products directly affect the conductivity of products, more salt, acid content, the conductivity is stronger, the larger the effect of relative products, it is difficult to detect, the sensitivity is low; the higher the temperature is, from the perspective of chemical molecular motion is stronger, more conductive strong, relatively detection will be difficult, but if you can reduce the frequency of equipment, product compensation, pressing the product effect, can not bear a grudge relative save this factor.

4. The factors of the testing machine itself

The factors of the tester itself include the size of the opening, the frequency of the machine, the speed of the operation and the size of the belt signal. The larger the opening size is, the lower the detection sensitivity, the smaller the opening size, and the higher the relative detection precision. The higher the frequency of the machine, the higher the sensitivity of the corresponding detection.
