Electronic scales are widely used in control, batching and metering, which often require very high system accuracy. One of the main reasons that affect the accuracy of the system is the nonlinear problem of the electronic scale. This paper focuses on the main causes and solutions of nonlinear errors from the perspective of practice and application.
Electronic scales used by various departments, enterprises and institutions as the highest measurement standards, as well as electronic scales used for trade settlement, safety protection, medical and health care, and environmental monitoring, can only be used after metrological verification. Those who fail to apply for metrological verification or fail to pass the verification shall not be used.
Extended data:
The electronic scale of the loader measures the change of the cylinder pressure during the lifting of the boom through two pressure sensors respectively installed on the oil inlet and return paths of the boom cylinder of the loader.
Adjust the speed, and the central processor in the on-board instrument will automatically calculate, so as to obtain the weight data and display the obtained weight on the instrument screen.
According to the manufacturer's statement, the accuracy grade of loader electronic scale should meet the requirements of Y(b) scale. The nameplate, panel or meter head of the loader electronic scale shall be marked with the marks of measurement system and measuring instruments, and their marks, numbers and descriptions must be clear and reliable.
