【摘要】 电容液滴传感器是利用液滴头和环形极板组成的特殊电容传感器,将液滴体积的变化转化成电容量的变化,从而间接测量液滴的体积。文中具体介绍了电容液滴传感器的工作原理,同时给出随液滴生长过程液滴体积的变化规律,并用图像处理的方法对液滴体积进行计算,得到基于频率的液滴体积变化曲线。更多还原

【Abstract】 The capacitive drop sensor is a special capacitive sensor,which is made up of drop head and loop electrode,the variety of drop volume is inverted to the capacitive value,then test the drop volume indirectly.Introduced the theory of capactive drop sensor,got the variety of drop volume relative to the dripping process of the liquid drop and use the image processing to compute the drop volume,then get the drop volume curve based on frequency.更多还原
