Why does the checkweigher show that the weight jumps up and down
It is a normal phenomenon that the weight displayed by the checkweigher jumps up and down. The working principle of the checkweigher machine is that when the product passes through the weight detection table, the weight sensor transmits the sensed weight to the AD converter as an analog signal, and then the AD The converter is sent to the system, and the system is sent to the display for display. Because the precision checkweigher adopts high-precision weight sensor, the weight sensor is very sensitive to everything in the outside world, including wind blowing, airflow, etc., so under normal circumstances, the weight of the checkweigher machine display is 0.1~0.2g. normal phenomenon. However, if the weight of the monitor jumps up and down to 1g or even higher, it is abnormal and needs to be stopped for inspection. When the weight range of the checkweigher is too large, the inspection items generally need to be checked: 1. Check whether there is dust on the sensor; 2. Check whether there is any object against the pallet; 3. After checking the above two steps, press the weight reset button, Recalibrate the scale.
