Average Transformation Theory--Based Capacitive Level Sensor with Anti-Attachment;
基于均匀传输线理论的防挂料电容物位传感器的设计与研究
Based on the theory of average transformation,the electric attachment resistance is equal to the value of capacitance between sensor electrode and attachment.
从均匀传输线理论出发 ,推导出电容式物位传感器挂料层的电阻与传感探极和挂料层以绝缘层为介质所形成的电容的容抗在数值上相等 ,由此得出通过测量传感电极的复数阻抗来消除挂料误差对测量的影响。
Probe attachment isn抰 existed in such sensor.
射频导纳物位计解决了导电介质物位测量中的挂料问题,适合于火电厂的灰粉测量。
