With the advancement of technology, the electronic weighing system with the load cell as the core has been widely applied to all walks of life, realizing the rapid and accurate weighing of equipment materials, especially with the emergence of microprocessors, industrial The automation of the production process has been continuously improved. The weighing system in the sensor has become an essential device in the process control. From the weight scales of large tanks and hoppers that could not be weighed before, the batching system for mixing and distributing various raw materials is measured. The weighing system is applied to the automatic detection in the production process and the control of the amount of powder and granules. At present, the weighing system is used in almost all weighing areas.
According to the load characteristics of the load cell in practical applications, the load cell is divided into two types, the static load weighing module and the dynamic load weighing module. The static load weigh module is suitable for applications where only vertical forces are applied. Such as tank, storage hopper weight detection. The dynamic load module is suitable for occasions where the force is obvious. Such as platform, production line, conveyor belt weight detection. The weighing system is a new type of weighing element that combines components such as load cells, load transfer devices and mounting connections. It can be easily connected to mechanical devices of various shapes, such as raceways and platforms. , vertical tanks, tanks, hoppers, etc. The electronic weighing system with the weighing module as the core can ensure the high precision of the weighing and the long-term stability, and solve the weighing error caused by improper installation. Systems using weighing modules are theoretically capable of achieving a weighing accuracy of better than five tenths.
 However, the resistance strain type weighing module in the electronic weighing system is based on the principle that the elastic body is elastically deformed under the action of an external force, so that the resistance strain gauge attached to the surface thereof is also deformed together, and after the resistance strain gauge is deformed, its The resistance value will change, and then the corresponding measurement circuit converts this resistance change into an electrical signal, thereby completing the process of converting the external force into an electrical signal. It can be seen that the resistance strain gauge, the elastomer and the detection circuit are indispensable parts of the resistance strain type load cell. Taking a typical chemical tank as an example, a weighing module installed at the bottom of the tank transfers the weight signal of the tank to the junction box. The signal of each weighing module is connected in parallel in the junction box, and the angular difference can be adjusted according to the load condition of each weighing module, and the collected weight signal is sent to the weight transmitter. The weight transmitter processes the weight signal into the corresponding weight data output to the control system, so the load cell will be an indispensable component in any weighing field.
