摘要
为了实现在制药行业中对胶囊的装药量是否合格进行在线快速检测,介绍一种用电容传感器采用变介电系数法实现对胶囊装药量的在线快速检测方法,电容量的检测采用高精度电容转换器AD7746集成电路,通过单片机对所测数据进行处理,判断所测胶囊是否合格,经实验证明达到了设计要求。
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.
