The electronic Feeding belt scale transmits the weight signal of the material on the belt and the speed signal of the belt to the on-site totalizer through the front channel weighing equipment and the rear channel weighing equipment installed on the conveyor. Inside the on-site totalizer, the weight signal is converted to a digital quantity by AD and transformed into a weight value by the built-in microcontroller; the speed pulse is transformed into a speed value by the built-in microcontroller and multiplied by the weight value to obtain the instantaneous flow rate; the two channels accumulate the instantaneous flow rate at the same time to obtain the totalized amount of the material in the two channels respectively, which is saved in the internal non-volatile memory. When the two channels are normal, the remote display adopts the average value of the accumulated quantity of the two channels, and if one of the channels fails, the normal one will be displayed.

The load cell commonly used in Operation electronic belt scales consists of a load cell bracket that contains a load cell that can detect tension, a load cell bracket that can vary the degree of tension, and a load cell pressure device that can detect variations in the degree of tension. These three components reflect the magnitude of the belt's tension and convert them into an electronic signal output.

The Measurement belt scale adopts three groups of weighing bridge, one of which is installed at the back of the belt conveyor feeding point, where no material passes through, and can only weigh the tare, which can realize real-time online automatic peeling when conveying materials; The other two groups of scales are installed in the front of the blanking point, and weigh the material at the same time during the conveying process, and compare and calibrate the material online.

The main control part of Drop automatic belt scale adopts PLO programming controller (PLC), which is composed of CPU module, I/O module, high-speed counting module, AD/DA module and scanner module. It is responsible for the entire digital quantity input and output control and provides the input and output signals required for external connection. It is used for frequency conversion speed regulation control and current instantaneous flow output 4-20mA current signal, the speed adjustment signal after computer processing is sent to the inverter by NI04I, and the encoded pulse from the speed encoder is sent to the high-speed counter by PLC calculation to obtain the running speed of the belt.

Central Control Automatic Belt Scale is an example of a belt scale with a fully suspended weigh frame formed by the support of four load cells, which are divided into four independent signals into the field digital converter. The belt is used for continuous feeding during the feeding process and the feeder delivers the material from the user's silo or other feeder and weighs it through the weigh bridge.

Electronic crane scales are mainly used as the core chip to measure the force, the main part of the force measurement principle for hook scales are bent elastic steel, deformation of the load cell and the scale body is an integrated unit, the weighing scale unit is hung on the hook of the lifting machinery, powered by rechargeable batteries; the display unit is placed on the ground on the operating platform, the operating platform can be 100-400m away from the site of the crane. The operating platform is located on the ground at a distance of 100-400 m from the site of the lifting machine, and the electrical signals of the weight are transmitted in the form of coded carrier waves through the radio transmission device on the weighing unit, and the receiving device on the weighing controller unit accepts the signals and sends them to the microprocessor for processing, and then finally displays the mass of the object to be weighed or prints out a record.

The weighing conveyor is used for the quantitative feeding of bulk materials, the feeding process is a spiral rotating continuous feeding, the materials from the user feed bin or other feeding equipment will be transported and through the weighing bridge for weight detection; at the same time installed in the end of the speed sensing screw for speed detection; the detected weight signal and speed signal together into the weighing controller for calculus processing and display in tons per hour unit of instantaneous flow and cumulative amount in tons per hour. Instantaneous flow rate in tons per hour and cumulative flow rate in tons per hour are displayed.

The weighing conveyor utilizes a load cell made of strain resistors for metering. The bearing surface generates a certain amount of pressure, and the material on top of the belt passes through the bearing surface of the lever device. This pressure is transmitted to the load cell through the lever device, and the control device will amplify and process the weight pressure signal sensed by the load cell, and then display it in a digital way. At the same time can be displayed on the digital signal for external human control, so that the measurement of belt scales according to people's actual requirements of the amount of feed automatically change the speed of the belt fast and slow, the given amount of feed tracking, so as to form a belt on the material more, slower, less material faster, no material when the speed of the fastest, and overloaded when the slowest and even will stop the control characteristics.

The weighing conveyor utilizes a load cell, a weighing controller, and an inlet and outlet conveyor. The load cell is used to collect the weight signal and send it to the controller for processing. The in-feed conveyor is used to provide adequate spacing between the products by means of speed. The outfeed conveyor is used to transport the finished product out of the weighing area. When the controller gets the weight signal of the product, the system will compare it with the pre-set weight range and sort the product, the sorting type will be different according to the application.
