Sensitivity detection method of food metal detector
1. Currently, food metal detectors have a variety of inspection methods, using different inspection methods such as digital dual frequency, digital single frequency, and simulation machines, and their corresponding inspection sensitivities are also different.
2. The difference in the size of the inspection port of the food metal detector will also affect the sensitivity. The smaller the inspection port, the higher the sensitivity. Similarly, the smaller the contact surface between the inspection item and the inspection probe, the higher the inspection accuracy will be.
3. Apart from the composition of the food metal detector itself, the characteristics of the inspected objects must also be considered. Since the product effect is an important factor affecting the sensitivity of the food metal detector, packaging materials, temperature, shape, moisture content, etc. will cause greater The product effect affected by this situation needs to be adjusted according to different situations;
4. In addition to the food metal detector and product components, you must also pay attention to the application environment of the food metal detector. If there are metal, magnetism, vibration and other components around the environment, it will cause certain interference to the inspection of the equipment, resulting in substandard sensitivity. situation, which needs to be avoided.
Food metal detector operation
1. Change the frequency
Since different products themselves produce different product benefits, if inspections are still carried out at the same frequency, inspection errors may easily occur. Therefore, for some products such as meat, cheese, and seafood, the inspection frequency must be adjusted accordingly. Otherwise, false alarms may easily occur. Targeted adjustments should be made according to different product characteristics, which can lead to more accurate inspections!
2. Multi-frequency feature identification
Food metal detectors are currently equipped with a variety of frequencies. Using two or more frequencies to operate can achieve certain results and improve the detection sensitivity of metals. This method is considered a compromise solution, but it improves the inspection of stainless steel. limited!
3. Understanding of characteristics
You can also use the building's characteristic recognition function of product effects, use intelligent identification methods to identify the difference between metal and product effects, and improve the working performance of metal detectors to generally achieve good inspection results.
