For products in many industries, the accuracy of CE approved x ray device factory has an important impact on quality assurance, but the accuracy of metal detector equipment is affected by many factors.
How can metal detectors perform more accurate?
First, change the frequency
Since the product benefits generated by digital fluoroscopy x ray machine manufacturer are not the same, if the same frequency is used for inspection at this time, it will easily cause detection errors. Therefore, for some products such as meat, cheese, and seafood, the equipment frequency must be adjusted accordingly for detection, otherwise the equipment is prone to false alarms and targeted adjustments based on different product characteristics can bring more accurate detection!
Second, multi-frequency feature recognition
Nuoding’s metal detectors are currently equipped with a variety of fluoroscopy x-ray device supplier. Using two or more frequencies can achieve a certain effect and improve the detection sensitivity of metals. This method is a compromise solution, but for stainless steel the detection improvement is limited!
Understanding of characteristics
You can also use the device’s feature recognition function for product effects, and use intelligent identification methods to distinguish the difference between metal and product effects. Improving the working function of metal detectors can generally achieve good detection functions, but the detection requirements for aluminum foil packaging products are special Customized, at present Nording can provide aluminum foil metal detector equipment!
The above are several methods for more accurate detection of digital radiography x-ray machine price. Of course, the detection accuracy has a great relationship with the detection equipment. Nording can currently provide high-precision metal detector equipment for different industries to escort product quality!
The same as is for the rest
First, change the frequency
Since the benefits of 4kw x ray system company are not the same, if the same frequency is still used for inspection at this time, it is very easy to have detection errors. Therefore, for some products such as meat, cheese and seafood, the frequency of the equipment should be adjusted accordingly for detection. Otherwise, the equipment is prone to false positives. Targeted adjustment should be made according to different product characteristics, which can bring more accurate detection!
Second, vehicle use x ray unit price
Nording’s metal detectors are currently equipped with a variety of frequencies. Working with more than two frequencies can achieve certain effects and improve the detection sensitivity of metals. This method is a compromise solution, but the detection improvement for stainless steel is limited.
Third, the understanding of characteristics
You can also use the feature recognition function of the x-ray system for clinic supplier on the product effect, and use the intelligent identification method to distinguish the difference between metal and product effect. Improving the operation function of the metal detector can generally achieve good detection function, but the detection requirements for aluminum foil packaged products are specially customized. At present, Nording can provide aluminum foil type metal detector equipment!
The above are several methods for metal detectors to carry out more 100mA DR x ray machine manufacturer. Of course, the detection accuracy has a great relationship with the detection equipment. Nording is currently able to provide high-precision metal detector equipment for different industries to protect the product quality!
Modern metal detector systems can identify all metals in food, non-food and drugs, including ferrous metals (chromium, steel, etc.), non-ferrous metals (copper, aluminum, etc.), and magnetic and non-magnetic stainless steels. The X-ray foreign body detector system can also detect metal and nonmetal pollutants, such as glass, ore, calcified bone, high-density plastic and rubber compounds. These detection systems can be installed at CCP to detect foreign raw materials before processing. These systems can also be installed at the middle or end point of the production line or packaging line.
Although metal detectors and X-ray foreign body detectors can provide various functions 9, their pollution detection methods are not foolproof. There are usually some areas of overlap between the two technologies, and careful consideration must be given to which is best suited to the application and budget at hand. For example, metal detection is considered the most appropriate technology for aluminum contamination in non-metallic packaging. Aluminum is a light metal and a good electrical conductor. Because its ray absorptivity is lower than that of other metals (such as iron and stainless steel), it will lead to a decrease in sensitivity in the X-ray foreign matter detector system. In other words, the size of aluminum contamination needs to be twice that of metal and stainless steel in order to achieve equivalent detection results. On the other hand, due to the excellent conductivity of aluminum, metal detector technology can usually be used to detect smaller sizes, so the latter is usually a better solution.
However, when testing the metal contamination in aluminum foil packaging, the choice is inclined to the other side. Metal detectors are difficult to find contaminants in aluminum foil packaging. However, due to the working mode of the X-ray system, the influence of aluminum packaging materials on the detection level can be ignored. The X-ray foreign matter detector can directly see through the low-density foil paper to better detect the metal contaminants in the package, which will provide a better solution in this case. The simplest way to choose metal detector or X-ray foreign body detector is to start from application. The first step is to carry out hazard analysis and critical control point (HACCP) audit or hazard analysis and risk-based preventive control (HARPC) audit. The detailed differences between HACCP and HARPC10 will be described separately, but basically, HARPC also includes aspects such as potential terrorist acts and/or vandalism and food fraud.
Such audits will help understand the requirements of 600mA DR x-ray device price related to compliance with GFSI and/or major retail groups in gfsi. HACCP audit will determine the pollution risks introduced into the manufacturing process and the types of pollutants that may be encountered. Critical Control Points (CCP) should be established to reduce risks, and product testing equipment should be installed at these points to reduce pollution risks to an acceptable level. HARPC audits also cover pollution in the manufacturing process, but also consider other security, such as visitor access and control. Suppliers and recall procedures are also more formal. HARPC system requires food factories to determine and implement prevention and control measures based on science or risks, rather than critical control points (CCP).
Whether HACCP or HARPC methods are used, appropriate technologies should be selected according to the pollution risks during production, which are the same. If the audit determines that metal is the only pollutant that may be found, then metal detectors may be the best solution. Similarly, if it is determined that other pollutants may be encountered, such as glass, stone or high-density plastic, the UC Arm digital x-ray system factory is more suitable. In either case, product testing is recommended to establish the most appropriate technology. In many cases, there is only one suitable solution: metal detector or X-ray foreign body detector system. However, it may be necessary to install metal detectors and X-ray foreign matter detector systems on different CCP in the same food environment and the same production line at the same time.
For X-ray, CT, B-ultrasound, MRI, these commonly used imaging examinations, many people can not distinguish clearly. Now, Xiao Bian compares the body to food and tells you intuitively how these tests play different roles.

X-ray: It’s like squashing bread
X-rays will pass through the human body and will not be exposed on the negative when they encounter the blocked part. After the film is developed, this part will be white. Like a piece of bread or a piece of cotton, you can’t see the fiber texture inside, but it will be clearer if you press it down with your hand. The biggest disadvantage of X-ray is that the images of deep and shallow tissues overlap and hide from each other, which sometimes requires multiple multi-angle X-ray films.
CT: Look like slicing bread
The principle of CT examination is that X-rays pass through the human body in layers, and then are computed by a computer for secondary imaging, just like cutting a piece of bread into slices. The advantage is that it can be seen in layers and more organizational information can be displayed after calculation.
B ultrasound: like picking watermelons, knock before picking them.
The principle of B-ultrasound is to use ultrasonic waves to penetrate the human body. When the sound waves meet the human body tissue, they will generate reflected waves, which are imaged by calculation. Just like picking watermelons, one needs to knock first before judging the situation.
Nuclear Magnetic Resonance: Shake and See
The magnetic resonance machine uses a relatively strong magnetic field to make the magnetic field lines of all water molecules in the human body in the same direction. At this moment, the magnetic field of the magnetic resonance machine suddenly disappears, and the magnetic field lines of water molecules in the human body suddenly return to the original randomly arranged state. Repeated application of magnetic field suddenly disappeared, and the MRI opportunity obtained sufficient data and imaged after calculation. Simply put, it is equivalent to shaking the water molecules by hand, making them vibrate, then calm down and feel the vibration inside. Therefore, magnetic resonance imaging (MRI) is also said to be a “shaking examination”.
What kind of examination are the four imaging methods applied to? When seeing a doctor, doctors often issue various imaging checkups: ultrasound, CT, MRI … Many patients will question the doctor’s intention to issue expensive checkups. In fact, doctors choose different imaging examinations according to different conditions.
1. Traumatic bone-Take a rough look at the X-ray film and examine various CT traumas. If you suspect that a bone has been injured, give priority to the X-ray film. The examination results are quick and easy to obtain. For further observation, CT can be selected. Ultrasound and nuclear magnetic resonance can’t clearly see the bone cortex and medulla, so they are generally not selected.
2. Cervical vertebra and lumbar vertebra-MRI is the best choice, CT is the second choice, cervical spondylosis, lumbar intervertebral disc herniation and other diseases need to observe intervertebral disc and corresponding nerve roots. To better observe these soft tissues, MRI is the best choice. Similarly, MRI is also the first choice for joint, muscle and adipose tissue examination.
3. Chest-A rough look at the X-ray film and a close look at the CT X-ray film can roughly check the heart, aorta, lung, pleura, ribs, etc. It can also check for increased lung texture, pulmonary calcification, aortic calcification, etc. Chest CT examination shows a clearer structure, and its sensitivity and accuracy in detecting chest lesions are better than conventional chest X-ray films, especially for the early diagnosis of lung cancer. However, the radiation dose of CT examination is higher than that of X-ray. Nuclear magnetic resonance is very limited in the diagnosis of lung diseases.
4. Abdominal Pelvic Cavity-Except intestinal tract, general ultrasound can check that abdominal organs are greatly affected by respiration, thus affecting CT and MRI, while ultrasound will not be affected. At the same time, ultrasound has high diagnostic accuracy for liver, spleen, pancreas, kidney, pelvic organs, etc. However, ultrasound is greatly disturbed by gas. For organs with more gas, such as intestinal tract, the accuracy of ultrasound diagnosis will decrease.
5. Heart-CT is used to exclude coronary heart disease, and conventional cardiac structure and function examination is used to check cardiac function. The information provided by cardiac color Doppler ultrasound is sufficient and simple. Coronary artery can be examined by CT, but coronary artery CT examination has a large amount of radiation and is not suitable for routine physical examination. Although nuclear magnetic resonance has no electromagnetic radiation, the observation of coronary artery is not as good as CT. Cardiac MRI is the “gold standard” for evaluating the structure and function of the heart.
