Weighing module acquisition system is composed of weighing sensor, weighing instrument and data acquisition module. The computer system consists of configuration software platform, application software and industrial control computer. The multi-protection system has three protection functions, pressure protection, crash "watchdog" protection and safety valve protection. Using the MCGSE configuration software platform, the weighing signal sends out a number of high-level switch trigger signals, the trigger signal drives an intermediate solid relay, and the relay drives the liquid discharge electric valve of the metering device to ensure the need of quantitative control when the computer is working normally.
020-34563445A high-precision weighing module is a device used to accurately measure the weight of an object, usually consisting of sensors, signal processing circuits, analog-to-digital conversion (ADC) circuits, microcontrollers, displays, and power supplies. Weighing module can realize the automatic weighing, counting and identification of items, modular design, its main functions are as follows:
Accurate measurement: The high-precision weighing module can convert the weight of the object into an electrical signal, which is displayed after processing by an electronic circuit, and has high measurement accuracy and stability, which can meet the needs of different occasions and industries for accurate measurement.
Intelligent functions: High-precision Weighing modules usually have some intelligent functions, such as peeling, user calibration, etc., which can help users more convenient weighing operations.
Data processing: High-precision weighing modules are usually integrated with advanced algorithms and software that automatically identify and correct errors, provide accurate weighing results, and can be seamlessly integrated with other equipment.
Wide application: High-precision weighing modules are widely used in many industries and fields, such as logistics and warehouse management, health and fitness, industrial automation and weighing and measurement.
Easy installation and maintenance: High-precision weighing modules usually have the characteristics of simple structure, easy installation and low maintenance cost, and users can quickly install and maintain.
Safety protection: Some high-precision weighing modules also have safety protection features, such as overload protection and anti-overturn design, which can protect equipment from damage and ensure safe operation.
