Electronic belt scale refers to the automatic weighing device for continuous weighing of bulk materials on the conveyor belt without subdividing the mass or interrupting the movement of the conveyor belt. Classification by belt speed: single speed belt scale, variable speed belt scale.

Electronic belt weigher load-bearing device of the scale structure mainly has double lever multi - roller, single - roller, cantilever and suspension four kinds. The measuring section of electronic belt scale with double lever multi-roller and suspension type balance is longer, generally 2 ~ 8 sets of idlers, high measuring accuracy, suitable for the place with large flow rate and high measuring accuracy requirements. The belt speed of the electronic belt scale with single idler and cantilever scales can be determined by the manufacturer and is suitable for areas where the flow is small or where the flow is used to control the batching.

Weighing display mainly has two kinds of digital display and Chinese character display, Chinese character display is a digital display upgrade product. The weighing display has accumulative and instantaneous flow display, with automatic zero adjustment, semi-automatic zero adjustment, self-check fault, digital calibration, flow control, printing and other functions. Chinese character display can also display speed. Chinese character display in the operation of the function display, can better help the use of personnel operation. Electronic belt scale, by the scale frame, speed sensor, high-precision weight sensor, electronic belt scale control display instrument, can be used for continuous dynamic measurement of solid materials.

The electronic belt scale weighing bridge is installed on the conveyor rack. When the material passes by, the weight of the material on the belt is detected by the metering idler and the lever ACTS on the weighing sensor, producing a voltage signal proportional to the belt load. The speed sensor is directly connected to the large-diameter speed measuring drum and provides a series of pulses, each pulse representing a belt motion unit, the frequency of which is proportional to the belt speed. The weighing instrument receives signals from the weighing sensor and the speed sensor, and obtains an instantaneous flow value and a cumulative weight value through integral operation, which are displayed separately.
