Electronic crane scales are used in many projects, but do you know how they work?
The working principle of the electronic crane scale is composed of electronic components such as load cells, amplification circuits, conversion circuits, microcontroller circuits, display circuits, keyboard circuits, communication interface circuits, and voltage-stabilized power supply circuits.
When the object is hung on the hook of the tension meter, pressure is applied to the sensor, which deforms, causing the impedance to change. At the same time, the excitation voltage changes and a changing analog signal is output. The signal is amplified by the amplifier circuit and output to the analog-to-digital converter. Convert it into a digital signal that is easy to process and output it to arithmetic control. This result is output to the display based on keyboard commands and the program. until this result is displayed.
