Recently, the non-contact measuring method of sensing has been adopted in many fields, for it can purify data eliminating the noise which is caused on insertion. It is important to use this measuring method in order to make a film thickness uniform, when we start to exchange or to produce various types of thermo-plastic film in the tubular film blowing process. The process stability depends greatly on the control of film thickness, particularly in the case where we must produce many kinds of products. However we can not use non-contact thickness sensors in the market on this tubular blowing process .From this viewpoint, we developed a new sensing system whose principle is different from usual thickness sensors (for instance, optical sensors). This new system not only compensates for the weakpoints of these usual sensors, but also can predict thickness profiles quickly in the early stage of production, to get a good yeild.
