The working principle of a weighing sensor is to stretch and thin the metal resistance wire under tension, and then increase the resistance, that is, the metal resistance changes with the strain it is subjected to. A weighing sensor is a conversion device used to convert weight or pressure signals into electrical signals. The construction principle of a weighing sensor is that the metal resistance has the characteristic of obstructing the flow of current. The explosion-proof weighing module can be easily installed on containers of various shapes, and can be conveniently used for loading, batching, or mixing in this container. By combining weighing sensors, instruments, and control systems. A system that controls the weighing and measurement of tank bodies. The Weighing system mainly consists of multiple sensors, multi-channel junction boxes (including amplifiers), display instruments, and output multi range control signals. The weighing module is a device that can convert physical or chemical quantities into easily usable electrical signals, convert input variables into measurable signals, and sense changes in acceleration force. Acceleration force is the force acting on an object during acceleration, which can be converted into electrical signals by G-sensors in various gravity changes such as shaking, falling, rising, and falling. After calculation and analysis by a microprocessor, it is transformed into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording, and control.
