The working principle of an electronic balance
Thread Content
I would like to ask my friends: What is the working principle of an electronic balance? Why is its accuracy so high? Why is a tray balance accurate to 0.1g, while an electronic balance can achieve accuracy of 0.001g, 0.0001g, or even higher?
An electronic balance can be divided into several components: a sensor, an amplification circuit, an A/D conversion circuit, a display circuit, a microcontroller, a memory, and a power supply. The sensor converts weight into a corresponding voltage signal; after amplification, this signal is sent to the A/D conversion circuit where it is converted into a digital value. The microcontroller then processes this value, and the weight is displayed directly on the screen.
Simply put, an electronic balance converts mechanical energy into electrical signals for display
