Electronic scale of the work process

time2010/10/14

  The working principle of electronic scale electronic components: load cell, amplifier circuit, AD converter circuit, microcontroller circuit, display circuit, keyboard circuitry, communications interface circuits, power supply circuits and other circuit. Let's us see electronic scale of the work process.

  When the object is placed on the pan, the pressure applied to the sensor, the sensor is deformed so that the impedance changes, using both excitation voltage changes a change in the output analog signal. The signal is amplified by the amplifier output to the ADC. Facilitate the processing of converting the digital signal output to CPU operation control.
