According to the principle of resistance strain gauge sensor, four strain gauges constitute the whole bridge, and apply a constant DC voltage at the power supply end of the bridge, the voltage at the output end of the bridge will be proportional to the pressure it is under, so the weight can be measured according to the difference in output voltage. The A/D converter CS5532 is Crystal's high precision 24-bit serial A/D converter. The highly integrated △-∑ A/D converter, thanks to the use of charge balance technology, its performance can reach 24 bits. This series of ADCs is ideal for applications such as measuring and weighing instruments, process control, science and medical.
020-34563445The automatic batching control system integrates computer technology, automatic control, communication technology and weighing technology. Its control function is perfect, display and operation are centralized, data processing is convenient, installation and maintenance is simple, and the system is easy to expand. In the structure of the computer centralized control system to solve the problem of "risk concentration", to achieve "management centralized risk dispersion", the system is stable and reliable to meet the use in the continuous production process. Dosing complete data acquisition and process control support a variety of communication protocols, to provide users with a variety of equipment support, colorful dynamic screen and the powerful functions of the system, so that you can easily operate, dosing control system has a strong scalability, easier to integrate with other systems, more effectively protect the user's investment.
Weighing dosing machine is composed of an industrial computer, a PLC programmable controller, powder dosing, liquid dosing, microdosing and control system. An automatic Weighing system which uses vacuum feeding, feeding screw quantitative feeding, weighing hopper automatic weighing of ingredients and cumulative weighing at the same time. Suitable for accurate measurement of materials and automatic batching operations in the production process.
The industrial machine is used as the upper computer (industrial computer, fully compatible with ordinary computers, more suitable for harsh industrial environment) + PLC+ weighing module (or weighing signal sampling sample) + load sensor + weighing actuator. Can include measurement control host (host computer), weighing software (measurement software/control software), plc weighing control instrument, weighing sensor, weighing bin also known as bucket scale, warehouse scale, the way can be incremental scale and reduction scale); And in most cases with the frequency converter control.
Distributed structure, good openness, easy to expand, stable and reliable performance "structure mode:" upper computer +PLC system + solid batching control instrument ", the connection of each part of the equipment using RS485 fieldbus, simple and reliable structure.
Weighing instrument adopts high quality controller, which has the characteristics of high precision, high reliability, strong anti-interference ability and so on. High precision weighing module is selected for the sensor. The weighing module is easy to install and maintain.
Computer monitoring and management function is powerful, real-time collection, timely display of operating conditions and relevant data, the picture image is realistic, dynamic; It can automatically complete the system batching process, and the computer screen displays the work flow of the weighing batching control system in real time. The software is simple to operate and the picture is realistic.
The upper computer software sets the operation password and password modification protection of important parameters, and the user realizes hierarchical management, and can arbitrarily define the rights of personnel. The intelligent report software provides a large amount of data information for production management, such as ingredient result list, raw material consumption list, production volume list, formula use result record, etc. It can produce statistics and print functions such as daily, monthly and annual reports according to time and formula.
Can automatically display or print fault time, nature and location, and sound and light alarm; The control mode can be divided into remote automatic, local automatic, local manual and local instrument control.
