The weighing module is elastically deformed under the action of external force, so that the resistance strain gauge attached to its surface is also deformed. After the deformation of the resistance strain gauge, the resistance value will change, and then this positive change will be converted into voltage by the corresponding measuring circuit, thus completing the process of converting external force into electrical signal. Among them, the resistance strain gauge is a strain gauge by mechanically distributing an electric limiting wire on a substrate made of organic materials.

The load cell of the belt scale is installed on the weighing bridge, when the belt is working normally, the detected weight of the materials on the belt will be transmitted to the weighing instrument, and the speed signal of the belt conveyor detected by the speed sensor of the belt scale will also be transmitted to the weighing instrument, which will convert the speed signal with the weighing signal and get the instantaneous flow rate and the cumulative output. The speed sensor is directly connected to the large diameter speed measuring pulley, and is used to provide a series of pulse data, each pulse represents a belt motion unit, and the frequency of the pulse is proportional to the belt speed of the conveyor.

Belt scale consists of steel mechanical weighing frame, speed sensor, high precision weighing sensor, electronic belt scale manipulation display instrument panel, etc. It can carry out continuous dynamic measurement and verification of solid materials. It is a fully automated electronic scale that continuously weighs the bulk material in the conveyor belt without the need for quality segmentation or termination of the conveyor belt movement.

The belt scale consists of a weighing bridge, load cell, speed measuring drum, speed sensor and accumulator. The load cell is mounted on the longitudinal beam of the conveyor, which supports the weighing rollers and detects the weight of the material on the belt, generating a voltage signal proportional to the belt load. The speed sensor is directly coupled to the driven pulley or to a large diameter pulley and provides a series of pulses, each pulse representing a unit length of belt run, at a frequency proportional to the belt speed. The accumulator receives the signals from the load cell and the speed sensor, and after A/D conversion, filtering and shaping, enters the microprocessor to perform arithmetic operations, and outputs the cumulative and instantaneous flow rate, the belt speed, the counting pulses, and other parameters.

Vertical reactor is an automatic production line for conveying, proportioning, heating, mixing and packaging of different types of materials (solid or liquid). It adopts PLC control mode and novel frequency conversion speed control feeding mechanism, which can realize the functions of material transmission, dosage control, formula design and production data management with the dosage control software package. And can realize the aggregate control of multiple batching systems through the network.

Weighing system is suitable for petroleum, chemical and proportioning industries. It is based on computer technology, control technology, communication technology and graphic display technology (i.e., 4C technology), and connects field control stations, control management stations, testing stations and operation management stations and engineer stations of operation and control centers which are distributed in the industrial site (nearby) through the communication network, and completes the decentralized control and the centralized operation and management in one integrated control system.

Weighing equipment in the production of powder and some inappropriate in the pipeline measurement of the media on the pro-measurement and control, a typical kettle weighing as an example; installed in the bottom of the kettle three weighing modules will be the kettle kettle weight signals transmitted to the junction box, the junction box will be the output of the weight module weight signals are connected in parallel to the weight terminals or weighing controllers, the weighing terminals or weight transmitter will be the weight signals are processed into the corresponding weight data. The weighing terminal or weight transmitter will process the weight signal into corresponding weight data.

Weighing equipment is a complete set of automation equipment to realize dynamic weighing and batching control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts the man-machine configuration, which controls the weight and flow of the material loaded into the weighing hopper according to the process requirements, through the monitoring system and the PLC program.

Mixing system is a kind of intelligent weighing system integrating control and management, with superior performance, stability and reliability. The product takes imported high-grade industrial computer as the mixing host, and combines with operation desk, analog screen and scale body to form a complete control system, and flexibly composes a machine and a scale and a machine and a scale according to the user's technological needs, and the selection of this system can greatly improve the enterprise's production efficiency and management ability.
