With the rapid development of computer technology and microelectronics technology, weighing sensing sensors have been used more and more widely. At present, electronic truck scale sensors are our. One of the most widely used products in China, it is used in building materials, grain, coal, electricity, etc. It is widely used in various fields such as mining and mining.

The structure and working principle of electronic truck scale sensor. Electronic automobile sensors are mainly composed of weighing indicators, load cells, interfaces

It is composed of wire boxes, carriers, connectors and other parts, and is equipped with computers, stable external devices such as power supplies and printers. How the electronic truck scale works. The principle of variable power measurement is used to convert non-electricity gravity into electricity for weighing.

It mainly consists of two parts, digital conversion module (A/D) and analog load sensor

Composed, combined with microelectronics technology and microcomputer technology, it can be automatically or manually. Automatically adjust the offset load, automatically modify the sensor number, and automatically. The sensor is addressed and data is read. Below the load cell elastomer there is. Strain bridge, install load cells under each weighing point of the weighing platform. Connect the corresponding cables in parallel in the junction box. When a car passes an electronic car. When the scale is weighed on the platform, the load cell will receive the force exerted on the weighing platform and pass. The strain bridge outputs electrical signals, and then the output electrical signals are linearly amplified. After that, it is passed to the A/D converter, which then converts the analog signal into. It is a digital signal, and the digital signal is then transmitted to the microcomputer processor. After the microcomputer processor. After processing, the weighing value is displayed in the display window, and finally, the weighing value is displayed by the computer and printer.

Store the vehicle's weighing values (gross weight, net weight, tare weight, etc.) in the computer, these data can be statistically managed and report printed through a computer.

Selection of electronic truck scale sensors. From the above analysis, it can be seen that the electronic truck scale uses the force-electricity conversion principle. A weighing device that converts non-electricity into electricity through processing, and to realize. From force to electricity conversion, the most critical device is the sensor. So, in reality. The selection of load cells in an application is very important. It is usually specified that when static, the electronic. The maximum load of the truck scale sensor = the number of sensors. The rating of the sensor Load 70%, because the vehicle will be impacted and vibrated when weighing during the dynamic process. Due to the influence of other factors, coupled with the weight of the weighing body itself, some sensors are. The weight on the scale is about 10% to 40% more than the actual load at that moment. Sometimes the rated load may be exceeded, causing the vehicle to be weighed at that time.

Accuracy decreases. In order to ensure that the sensor does not exceed its rated load during operation. With a specified coefficient of 70%, the accuracy of weighing is improved. Of course, in actual selection. Factors such as relevant technical parameters also need to be considered, especially sensitivity.
