| Abstract: | Air tight property for air proof containers is one of important factors which impact products. In this paper, differential pressure leak detector based on dsPICPIC30F6012 digital signal processor is introduced. The working principle, the air pipe loop construction, the system hardware circuit and software design are discussed. Here, keyboard input, LED display, print output and communication are designed, at the same time, FFT wave filter and temperature compensation are considered, high precision air-leakage detecting automation is realized. |
