The choice of the form of the weighing sensor mainly depends on the type of weighing and installation space, to ensure that the installation is appropriate, the sensor simulator can not only set and calibrate the weighing display instrument in the laboratory, but also find and find the cause of the fault in time on the spot, so as to quickly eliminate the fault, is an essential electronic truck scale detection and maintenance equipment. The simulator is similar to a DC standard voltage source and can provide analog voltage signals in various weighing ranges to the weighing display instrument. Load cell simulator is made according to the working principle of resistance strain gauge load cell. It can simulate various loading states of resistance strain gauge load cell.
The strain gauge of a load cell is mainly composed of a sensitive grid, a base, a covering layer and a lead. It converts the strain of the elastomer into a change in resistance value through the resistance strain effect of the sensitive gate. If the material itself has hysteresis, the strain gauge also has hysteresis. This is also a factor that must be considered when choosing a load cell.
