High-precision dynamic weighing machine is a professional high-precision dynamic weighing machine, which can meet the requirements of detection speed and accuracy in the industrial large-scale production of food, medicine, daily chemical and other industries, and has solutions to adapt to various production applications, effectively helping enterprises to find and remove products containing metal foreign bodies, and avoid waste caused by wrong removal while meeting the compliance requirements. In order to ensure that industrial metal detectors have high sensitivity, the following six aspects need to be paid attention to when installing:
1. The high-precision dynamic weighing machine can install 'plate' coils above or below the products transported on the conveyor belt.
2, it and the central coil connected to the oscillator will produce a high-frequency magnetic field.
(3) The two opposite receiving coils are connected to each other so that the induced voltage generated by them can be self-offset when the magnetic field is not disturbed.
4, in order to obtain the best sensitivity, the aperture size of the metal detector should match the specific product size.
5, the aperture is too small will not be easy for the product to pass on the conveyor belt, and the aperture is too large, there will be the danger of "weakening" the signal.
6, but the sensitivity of the detector is usually measured from the geometric center of the aperture of the least sensitive geometric point, so when the product is contaminated by metal through, it implies that the metal object will interfere with the magnetic field of the detector, thereby detecting the presence of metal impurities.
Metal detectors are mainly used in the detection of metal impurities in the food industry, which can be divided into belt type, pipe type, gravity fall type and other forms according to the production line in industrial production. When food or medicine with metal foreign objects passes through the device, it triggers an alarm from the metal detector and then is discharged. Metal detectors for food can be selected from Metler-Toledo, with excellent accuracy and stability to help companies achieve compliance in production.
The pharmaceutical industry also needs to use metal detectors in the production of drugs, drug production needs to meet the GMP regulations, which has the accuracy requirements for metal foreign bodies, which is also the most stringent requirements in all fields where metal detectors can be applied. Mettler Toledo's Tablex metal detectors help pharmaceutical companies achieve manufacturing compliance with outstanding precision and stability.
In battlefield archaeology, most of the evidence is metal, such as musket warheads, cartridges, bullets, cannons and shells, shrapnel and swords, depending on the historical period in which the battle took place. So the most important tool a battlefield archaeologist has is a simple metal detector.
Textile (food, medicine, clothing, clothing, toys, footwear) inspection broken needle, the special name is: needle detector, needle detector safety and anti-theft inspection of the special name is: metal detection door, security door, metal detection security door.
Metal buried in the ground, through the thick soil to detect, must be affected by the geological structure. The formation contains a variety of minerals, which can also cause metal detection to produce signals, and some mineral signals can mask the metal signal and create an illusion. Anyone who has used an old metal detector will have this experience, as the probe is close to the mound, rocks, bricks will emit an alarm sound, this phenomenon is called "mineralization reaction". For this reason, older metal detectors can only detect metal in shallow soil, and can do nothing about metal targets buried deep underground. Inu-god underground metal detector is equipped with an advanced ground balance system, which can eliminate the interference of "mineralization reaction", and greatly improve the detection depth and effect of the instrument.
The above is an introduction to the method of ensuring the sensitivity of industrial metal detectors, which is an instrument used to detect metals and has a wide range of applications in various industries. At first, metal detectors are mainly used in industry and mining, and now, metal detectors have undergone several changes, from the initial signal analog technology to continuous wave technology, and then to digital pulse technology, its sensitivity, resolution, accuracy, and performance have made a qualitative leap, and the application field has also expanded to industrial production, food detection, safety inspection and archaeological research.
