The principle of weighing machine_application of weighing machine

Weighing machine is a key equipment in the load industry. Many people may not understand it. Today, I will introduce in detail what is weighing machine and other basic principles and applications. I look forward to helping everyone understand the scale. Heavy Machinery. What is a weighing machine? Weighing machine is a kind of equipment that weighs the net weight, but it is different from the general weighing machine. It converts the net weight data signal of the object into an electronic signal, and displays the information of the net weight of the object according to the electronic signal. Device. The application of the weighing machine should consider whether the natural environment of the application is suitable, and the poor application of the natural environment will endanger its work. At this stage, there are many types of weighing machines on the sales market, such as optical, hydraulic, capacitive sensors, and magnetic force sensors. Each type has its own characteristics and applications. The principle of the weighing machine In the application of the weighing machine, there are three components that give full play to the key functions: polyurethane elastomer, resistance strain gauge and test power circuit. At the beginning of weighing, once the object is installed on the sensor, the polyurethane elastomer will be deformed due to the working pressure of the object, and the deformation of the polyurethane elastomer will cause the resistance strain gauge on its surface to follow the deformation, and the deformation of the resistance strain gauge It also causes its resistance value to change, and then the expansion or reduction of the resistance value will be converted into an electronic signal through the inspection power circuit, and then the information can be displayed to show the net weight of the object, so that all weighing is completed. Let’s introduce the three key positions of the weighing machine. The effect of polyurethane elastomer is very immediate. First, it must recognize the interaction force of external objects and use recoil force to bear the interaction force of this object. Then it needs to cause the transformation of the resistance strain gauge so that all the weighing can be carried out; the resistance strain gauge is a inherited component, which converts the interaction force of the polyurethane elastomer on it into the transformation of the resistance value, and then converts this kind of transformation information The composition of the resistance strain gauge is actually a heating wire and an organic material base. The extension of the heating wire can cause the transformation of the resistor; it is very important to check the efficiency of the power circuit, so it is necessary to check the power circuit. The strong anti-interference ability ensures that the data signal conversion is not easy to be harmed by the surrounding environment, so that the accuracy of the weighing can be guaranteed. The use of weighing machines Weighing machines are actually very common in the weighing industry, and many objects with a large net weight that cannot be weighed can be weighed by the weighing machine. For example, weighing trucks on highways. Nowadays, a weighing bridge will be built on highways. A weighing machine is installed on the weighing bridge, so that if trucks are driven on the weighing bridge, they can be weighed and inspected. Does it have the problem of overloading, so that even if the weighing work becomes more and more simple, it will not harm other motor vehicles. With the development of science and technology, the weighing machine is constantly improving, and I firmly believe that its main use will become wider and wider.

It has become necessary for Guangdong Kenwei Intellectualized Machinery Co.,LTD. to continually cultivate, develop and update their skills to work successfully alongside high-tech.
