Research of Leak Detection and Exclusion System Based on Pressure Differential Discrimination Method

Aiming at the detection problem of beverage bottle leak existing in beverage producing industry, a beverage bottle leak detection and exclusion system is researched. With the using of thermal plastic seal PET beverage bottle as testing object, the detection scheme and the feature recognition method for squeezing deformation value of beverage bottle are introduced, and the pressure differential detection and discrimination method with dual sensors is created. Also the relevant hardware circuits and software for leak bottle detection, squeezing device adjustment, leak bottle exclusion and data display etc. are designed. The results indicate that the system performance meets the practical function requirements.
