What are the reasons for the false alarm of the metal detector?
The metal detector will alarm and respond when it detects metal impurities, but sometimes false alarms occur, which will affect the production efficiency of products. So, what is the reason for the false alarm of the metal detector? Reasons for the false alarm of the metal detector: 1. Check whether there is a problem with the power supply, such as whether there is interference in the power line. If there is interference, it is recommended to use a power isolation transformer. Power the metal detector! 2. Check whether the sensitivity and phase settings are reasonable. If the sensitivity is too high or the phase changes, it will easily lead to an increase in the product effect, thereby identifying false alarms. However, food detection generally requires higher sensitivity! 3. Some metal detectors with poor quality are prone to interference, so it is necessary to check whether there is any frequency conversion equipment in operation near the metal detector. Frequency conversion equipment is likely to cause greater interference to the metal detector, thereby affecting the sensitivity of the equipment and false alarms. Response! 4. Check if there is a strong magnetic field or large metal blocks around the metal detector. These substances will change the magnetic field around the device and affect the normal operation of the device, resulting in false alarms!
