The check weigher mainly realizes the weighing function through weighing sensors and microprocessors. The weighing sensor is a platform for placing goods. lt can sense the weight of the goods and convert the gravity signal into an electrical signal. The microprocessor receives and processes these electrical signals and converts them into weight numbers to display on the screen. When the weighed product exceeds or falls below the set range, the system will automatically remove it to ensure the quality of the products on the production line.
