Scope of application
For many years, China has mainly used mechanical weighing equipment. In the 1980s, it began to expand the use of electronic weighing equipment and the development of large-scale automatic weighing equipment. China has been able to independently design and manufacture high precision and operation. Fast and accurate measurement of various electronic weighing equipment. Due to the rapid development of technology and the improvement of application level, the digitization, integration, networking and intelligence of weighing equipment will become the development direction and focus of the world weighing equipment industry.
Weighing equipment is used in chemical, commercial concrete, logistics, ports, terminals, factories and mines, businesses, railways and highways for bulk cargo
SCS series truck scale
The main weighing equipment of the quantity, the truck scale that was common before the 1980s is generally a mechanical truck scale that is purely mechanically constructed using the principle of leverage, also known as a mechanical weighbridge. The modern electronic weighing equipment adopts the newly designed steel structure carrier, which is simple and light, easy to carry. The electronic weighing equipment can be directly laid on the concrete floor and equipped with movable slope (optional) to make full use of the space. Four high-precision shear beam load cells and intelligent weighing display instruments form a weighing system.
Precautions for use
One is to warm up in advance. Weighing equipment usually needs to be preheated before use, and the preheating time of weighing equipment is often different. Generally speaking, the higher the accuracy level of the weighing equipment, the longer the warming time required, according to the weighing equipment. Preheating is required in the instruction manual, and the warm-up time can be extended if necessary (usually the lower the ambient temperature, the longer the warm-up time). In fact, many users are ready to use when using weighing equipment, so that the weighing performance of the weighing equipment cannot be guaranteed. Therefore, preheating of weighing equipment is the focus of accuracy.
The second is environmental conditions. Environmental conditions are also an important factor affecting the metering performance of weighing equipment. If the special temperature limit is not specified in the operating instructions of the weighing equipment, the weighing equipment should work normally at a temperature of -10 ° C to 40 ° C; if a special temperature limit is specified, the weighing equipment should be at the specified temperature. Work under conditions; weighing equipment also has requirements for the humidity of the environment. For example, a level I balance requires a relative humidity of no more than 80%.
The third is the horizontal state. Generally, high-precision weighing equipments are equipped with leveling devices and leveling devices. In use, the horizontal state of the symmetrical heavy equipment is often checked. In fact, some users often overlook the inspection of the horizontal state of the symmetrical heavy equipment (weighing equipment often causes four corners or uneven levels due to movement or other reasons), which is also the main reason for the data of the weighing equipment is not allowed.
Fourth, calibration is always available. Some people think that weighing equipment is accurate within the validity period after periodic verification, and often ignores the importance of calibration, even without calibration. As we all know, weighing equipment is often used in the use of environmental factors, human factors and other factors, measurement performance often changes slightly, which requires us to calibrate it in daily use. So, how do we calibrate? Weighing equipment should be calibrated daily or before each use, and the frequency of calibration can be increased if necessary. For the calibration weight, the higher the level, the better. Generally, the weight error should be no more than 1/3 of the maximum allowable error of the balance, and should be sent to the quality supervision department for regular inspection. If the error exceeds the standard, It is necessary to promptly send it to the quality supervision department for testing, so as to avoid the loss and the phenomenon of pitfalling consumers.
Weighing equipment is used in many applications in control, batching and metering. The system accuracy of symmetric heavy equipment is often very high. Weighing equipment is a traditional industry with a long history of development and an important basic industry. After the reform and opening up, China's weighing equipment industry has developed rapidly. The management system, industry structure, product structure, technical level and position in the national economy of the weighing equipment industry have changed tremendously. The enterprises of the equipment have developed quite a lot. Some early-starting enterprises such as Dacheng Weighing Equipment Co., Ltd. have played an indelible role in the progress of China's weighing equipment.
At present, China's application of high-tech advanced weighing equipment is still in the stage of relying on import to solve supply. Therefore, in the field of high-tech weighing equipment products, China's weighing equipment manufacturing enterprises have huge development space, Dacheng Weighing equipment hopes that more people can believe in domestic production and support our national industry. In addition, with the continuous growth of domestic consumption levels and industrial economy, domestic demand for weighing equipment products will further increase, serving merchants and corporate users.
