Working principle of mechanical and electronic health scales
For mechanical health scales, the device works on the principle of using springs to determine weight. Simply place the object to be checked on the scale, thanks to the natural working principle of the spring, after a short time the device will give you the desired information. Because it uses a spring, the mechanical health scale does not have to use electrical energy.
For electronic health scales, when you place an object on the device, the weight of the object will act on the scale and create a force that bends the metal bar, creating resistance. The electronic processing unit of the scale will be responsible for converting the received signals into results and informing the user.
