The detection accuracy of metal detectors is affected by many factors, the following are several main factors:
Detect shape and size of items
The shape and size of the detected item have an impact on the detection accuracy. For example, a metal detector may not be able to fully detect a metal foreign object when the item is small or irregularly shaped.
Detect physical properties of items
The physical characteristics of the detected items such as density and conductivity will affect the detection accuracy of the metal detector. For example, when the detection item contains a high density of metals, the detection accuracy may be affected.
Detect environmental factors of items
The environmental factors such as temperature and humidity of the detected items will also affect the detection accuracy of the metal detector.
Sensitivity settings for metal detectors
The sensitivity setting of the metal detector will directly affect its detection accuracy. If the sensitivity is set too high or too low, false detection or missed detection may occur.
Calibration and Maintenance of Metal Detectors
The calibration and maintenance of metal detectors are also important factors affecting their detection accuracy.If the calibration is not accurate or the maintenance is not timely,the detection accuracy may be reduced.
Therefore, in order to maintain the detection accuracy of the metal detector,it is necessary to fully consider these factors when selecting, using, calibrating and maintaining the metal detector, and operate in strict accordance with relevant specifications and requirements.
