Abstract
In order to realize on-line rapid detection of charge quantity of capsule in the pharmaceutical industry
a method which use capacitive sensor to measure the variable dielectric coefficient is proposed.Capacitance detection is realized by high precision capacitor converters AD7746 IC.The measured data is processed by the MCU and identify whether the detected capsule is qualified.The experiment prove that the design purpose is achieved.
