Hopper scales are used for weighing product streams for packaging, dosing, dispensing and yield monitoring in batches. The unit consists of a hopper, weighing cell and weighing instrument. It is an ideal automatic weighing device for the modernization of bulk materials, mainly divided into totalizing hopper scales and loss-in-weight feeding scales.

Aviation baggage scales in the original basis to adapt to the modernization of airport management measurement and management needs and improve the development of a new generation of products. With rapid and accurate weighing, rich and complete performance, easy to use and simple, aviation baggage scales are widely used in airports for passenger baggage measurement, management and loading and other needs.

The quantitative filling machine is controlled by PLC program for each sensor, relay, switch and solenoid valve, the empty barrel will be transferred to the filling position by the conveyor, the proximity switch arranged in the filling position will automatically sense the automatic filling to reach the predetermined weight, the PLC will control the filling gun to stop filling, and the suction cap device will automatically seal the cap, and start the conveyor motor to transport the filling barrel away.

Weighing conveyor is a kind of equipment that can carry out on-line dynamic weighing of materials. It is mainly composed of a belt suspended on the bracket, a weighing sensor and a control system.

The mixing system mainly realizes the automatic control of the whole system through the electronic scale, which mainly completes the functions of automatic feeding, discharging, transporting, mixing and stirring of materials. It adopts the centralized control method of industrial control machine dosage, which consists of a host and several slaves connected through the network, and the host will give the control task to each slave to complete.

Hopper scales realize material level control by weighing, the material can be liquid or granular solid. Usually 3 or 4 force sensors are used. The weight of the material is converted into an electrical signal by the force sensors and amplified by the amplifier in the measuring circuit for display, recording and data processing. It has automatic zeroing and weighing data processing functions.

The feeding system measures the weight by means of a load cell under the reactor scale frame to determine the weight of the material on the reactor. A digital speed sensor is mounted on the tail drum or rotating equipment and continuously measures the pulse output of the speed sensor at the feed rate, which is proportional to the screw speed. The velocity signal along with the weight signal is weighed and fed to the belt feeder controller to generate and display the cumulative/instantaneous flow rate. The feeder controller compares the flow rate to the set flow rate and the controller outputs a signal to control the inverter to achieve the dosing requirement.

Weighing module of sanitation truck is a weighing system product specially developed for online weighing of trash cans of sanitation garbage trucks, which is suitable for side-mounted compression and rear-mounted compression sanitation garbage trucks. The biggest feature of this product is that it can realize weighing in the process of garbage hanging and lifting, and can automatically accumulate the weight of garbage collected and the number of garbage bins.

Weighing conveyor through the weighing module installed under the conveyor, the weight of the material itself will act on the sensor when it passes through the measuring section of the conveyor, and then it will generate a millivolt signal, and at the same time, the speed sensor will provide a conveyor belt speed signal, and these two signals will enter into the weighing system at the same time and carry out the arithmetic operation, and then the weight data can be displayed.
