RF sensor for online determination of granular dielectric materials weight

摘要：

We have developed an electromagnetic cavity resonator based RF sensor for online determination of granular dielectric materials weight.This sensor is non-instrusive and detects the density of the granular materials using resonant peaks captured instantaneously.A laboratory prototype of the RF sensor has been constructed.The properties of the RF cavity were simulated by ANSYS,and confirmed using a vector network analyzer.Standard deviation of weighing errors of the RF sensor with horizontal belt for Tobacco shred,cabo and dry straw is less than 0.5%,1.5 %and 2%,respectively.
