The working frequency of metal detectors is usually related to the following factors:
The size and shape of the detection target: the working frequency of the metal detector is usually related to the size and shape of the detected object. Specifically, smaller objects require high frequencies for detection accuracy, while larger objects require lower frequencies for detection.
Electrical conductivity of materials
The electrical conductivity of a metal refers to the ability of the metal to conduct electricity under the action of an external electric field, which is related to the chemical composition of the metal. Different kinds of metal materials have different conductivity, so different frequencies need to be used to detect different metals.
Magnetic permeability of materials
Magnetic permeability refers to the ability of a substance to be magnetized under the action of an external magnetic field, which is related to the chemical composition and structure of the material. Magnetic materials typically have a higher permeability than non-magnetic materials, so low frequencies are required to detect magnetic materials.
Detection depth
The working frequency of the metal detector is also related to the detection depth. Typically, higher frequency metal detectors can detect shallower metal objects, while lower frequency metal detectors can detect deeper metal objects.
Environmental interference
During metal detection, metal objects in the surrounding environment may generate interference signals, so the working frequency of the metal detector needs to be quite different from the frequency of environmental interference to avoid false detection.
In short, the working frequency of the metal detector depends on the size and shape of the detected object, the electrical conductivity and magnetic permeability of the material, the detection depth and environmental interference and other factors.
