The weighing module takes the single chip microcomputer as the CPU of the system. The external circuit needs display circuit, keyboard input, power supply, communication interface, sensor and alarm. The sensing element is made of piezoelectric material, and the piezoelectric effect of charge is generated on the surface of the piezoelectric material after being stressed. This charge is amplified and transformed by charge amplifier and measuring circuit, and then it becomes the electric output proportional to the external force. Piezoelectric sensors are used to measure force and non-electric physical quantities that can be converted into force.
020-34563445Weighing module is a kind of detection device. The Batching system can sense the measured information, and can transform the sensed information into electrical signals or other required forms of information output according to certain rules. The batching system can meet the requirements of information transmission, processing, storage, display, recording and control.
