The capacitance thickness sensor was used on noncontact realtime thickness measurement of blow film. According to the characteristics of system processing, the fuzzy control system was constructed based on PLC. Uniformity of film thickness was achieved by controlling extrusion speed of the extruder and the traction speed of tractor. It is proved that this system has higher precision, better reliability and stability, which can satisfy the demand of actual manufacture.
