Workflow description:
When an object is placed on the scale, pressure is applied to the sensor, which undergoes elastic deformation, causing a change in impedance. At the same time, the excitation voltage changes to output a changing analog signal. The signal is amplified by an amplification circuit and output to an analog-to-digital converter. Convert it into a digital signal that is easy to process and output it to the CPU for operation and control. The CPU outputs this result to the display based on keyboard commands and programs. Until this result is displayed.
Functionality
The electronic scale adopts a modern sensor technology, electronic technology, and computer technology integrated electronic weighing device to meet and solve the requirements of 'fast, accurate, continuous, and automatic' weighing in real life, while effectively eliminating human errors and making it more in line with the application requirements of legal metrology management and industrial production process control.
history
According to research, the ancient evidence of the existence of weight scales dates back to 2400 BC to 1800 BC in the Indus River Basin (now within Pakistan). Prior to this, there were no standards or precision for measuring weight. In Egypt, weight scales can be traced back to around 1878 BC, but their use may have extended much earlier. The truly modern weight scale was improved and invented by Leonardo da Vinci. With the development of the electronic scale industry, many brands have gradually entered the Chinese market, and electronic scales are being used by more people. More and more electronic scale brands are becoming familiar to humans.
metrological verification
Electronic scales are mandatory measuring instruments, and their qualified products have standards for calibration division value e and subdivision value D, which are protected by metrology laws.
According to the requirements of the "Metrology Law of the People's Republic of China" and the "Catalogue of Work Measuring Instruments for Compulsory Calibration of the People's Republic of China", all electronic scales used as social public measurement standards, electronic scales used as measurement standards by departments, enterprises, and institutions, as well as electronic scales used for trade settlement, safety protection, medical and health, and environmental monitoring, must pass metrological calibration before use. Those who fail to apply for metrological verification according to regulations, or fail to pass the verification, shall not be used.
