Ultrasonic Double Sheet Sensor (double tension detection) system is designed based on the principle of ultrasonic, so it is free from the vibration, material and color of the object being inspected. The principle of double sheet detection is based on the reduction of ultrasonic signal strength by one or two materials.
Completely overcome the shortcomings of other similar products such as photoelectric, mechanical and other similar products , such as transparent film and thin metal sheet, solar silicon chip, PCB circuit board, coating machine thin sheet and so on can be accurately detected.
It is widely used in paper-making,stamping, instant noodle packers, food packaging, solar wafer production equipment, coating machine, automatic binding and other industries.
