When an object is hung on a tension gauge hook, pressure is applied to the sensor, which deforms the sensor, causing a change in impedance, while using a change in the excitation voltage to output a varying analog signal. The signal is amplified by an amplification circuit and output to an analog-to-digital converter. Convert into a digital signal for easy processing and output to CPU operation control. The CPU outputs this result to the monitor based on key commands as well as programs. until this result is displayed.
