Causes and countermeasures of false alarms of metal detectors

Under normal circumstances, the metal detector will issue an alarm when it detects metal impurities, but sometimes false alarms occur. What is the cause? How should we deal with it? 1. Check whether there is interference in the power line, If there is a lot of noise, please use a power isolation transformer to supply power to the metal detector. 2. Check whether there is a working frequency conversion equipment near the gold metal detector. The frequency conversion equipment will cause great interference to the metal detector. Please move the metal detector away from the frequency conversion equipment. 3. Check whether there are strong magnetic fields or large metal blocks around the metal detector. Strong magnetic fields and large metal blocks will change the magnetic field around the metal detector, resulting in false alarms. 4. Check whether the sensitivity and phase are in the initial position. If the sensitivity is too high or the phase changes, the product effect will increase, resulting in false alarms. Please re-adjust the product signal suppression. The above is the introduction of 'causes and countermeasures of false alarms of metal detectorsGuangdong Kenwei Technology focuses on the research and development, production and sales of metal detectors, metal separators and metal detectors, and provides professional metal detection solutions.
