Reasons and countermeasures for abnormal alarms of metal detectors
The metal detector will alarm and respond when it detects metal material residue, but sometimes the alarm is inaccurate, which will affect the production efficiency. Then do you know what happened to the abnormal alarm of the metal detector? How to solve it? 1. If the metal detector alarms abnormally, first check whether there is a problem at the switching power supply level, such as whether there is intrusion in the switching power supply route, If there is an intrusion situation, it is recommended to use switching power supply isolation transformers to develop the power supply system for food metal detectors! 2. Check whether the settings of sensitivity and position are effective. If the sensitivity is too high or the position is changed, it is very easy to To expand the utility of the commodity and thereby identify incorrect alarms, only food safety testing usually requires a higher sensitivity. 3. Some food metal detectors with weak quality are very easy to suffer from dryness. Therefore, it is necessary to check whether there is any DC frequency conversion machinery and equipment around the metal detector. DC frequency conversion machinery and equipment are very easy to cause great damage to the metal detector. 4. Check if there is a strong magnetic field or a large metal block near the metal detector. This chemical substance will change the electromagnetic field around the metal detector. , and then all the machinery and equipment are working normally, and then a false alarm occurs! In order to ensure the safety factor of food and remove the risk of environmental pollution of metal materials, food companies have standardized regulations on metal detectors at this stage. As a professional manufacturer of metal detector equipment, Kenwei Technology can provide metal detectors, metal separators and other products with stronger characteristics, higher sensitivity and workability at this stage.
