When the measuring plate moves, it drives the measuring end of the first displacement sensor to move. The first displacement sensor generates an electrical signal to display the specific width data through the display. Then, the plate is inserted between the supporting cylinder and the moving cylinder. The moving cylinder moves upward due to the squeezing. The moving cylinder drives the measuring end of the second displacement sensor to move through the movable ring. The second displacement sensor generates an electrical signal to display the thickness data of the plate through the display. The width and thickness of the plate can be automatically measured without manual measurement by workers, which reduces the workers' operation steps.
