Working principle of belt scale

The weighing bridge is generally installed on the conveyor frame, and the material generally acts on the idler. Through the
lever principle, we transfer the weight of the idler to the weighing sensor, which generates a voltage signal proportional to the weight of the material;
Then the speed sensor is directly connected to the large-diameter speed measuring drum. When the drum drives the belt to rotate,the speed measuring sensor will generate a series of pulse signals proportional to the speed, which will be transmitted to the instrument,

Through integral calculation, the instantaneous material mass is obtained, and through continuous cumulative calculation, the material mass on the whole belt is obtained, so as to achieve accurate dynamic weighing, and finally displayed on the instrument.
