The measurement formula of the weighing sensor in the weighing instrument is inseparable
Measuring method that the load cell cannot be separated


Let us introduce the weighing principle: According to the load cell's characteristics 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 weighing module is suitable for applications where only vertical force is applied, such as the inspection of the tank and the storage hopper. The dynamic load module is suitable for applications where the force is significant. Such as channel, production line, conveyor belt component inspection, weighing system is a new type of weighing element, it combines weighing sensors, load transfer equipment and device connectors, etc., can be very convenient and various shapes Mechanical equipment is connected, such as raceways, channels, vertical tanks, tanks, hoppers, etc. The electronic weighing system centered on the weighing module can ensure high precision of weighing, long-term stability and good handling. Weighing errors due to improper installation. The system using the weighing module can theoretically achieve a weighing accuracy of better than five-fifths.


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 his outer surface is also accompanied by deformation, and after the resistance strain gauge is deformed, its The resistance will change.
Then the corresponding measurement circuit converts this resistance change into an electrical signal, and then completes the process of converting the external force into an electrical signal. It can be seen that the resistance strain gauge, the elastomer and the inspection circuit are not in the resistance strain type load cell. The first few are missing. In a typical chemical tank, the weighing module at the bottom of the tank transfers the component signal of the tank to the junction box. The junction box is connected in parallel with the weighing module signal, and According to the load condition of each weighing module, the angular difference is modulated, and the component signal is sent to the component transmitter through the aggregated component signal. The component transmitter processes the component signal into corresponding component data and outputs it to the control system, so the load cell will be any The weighing category is not a missing component.
