What is the working principle of electronic belt scales?

Time:2020.12.17     News sources: Hebei Chaoda Sealing Products Co., Ltd
The weighing bridge of the electronic belt scale is installed on the conveyor frame. When the material passes by, the metering roller detects the weight of the material on the belt machine and acts on the weighing sensor through the lever, generating a voltage signal proportional to the load of the belt. A weighing sensor is mounted on the weighing bridge on the belt scale. When working, the material weight detected on the belt is sent to the weighing instrument. At the same time, the speed signal of the belt conveyor from the speed sensor is also sent to the weighing instrument. The speed sensor is directly connected to a large diameter speed measuring drum and provides a series of pulses, each of which represents a belt movement unit. The frequency of the pulse is proportional to the belt speed. The weighing instrument receives signals from the weighing sensor and the speed sensor, obtains an instantaneous flow value and accumulated weight value through integral operation, and displays them respectively.
