A sensor with high sensitivity and good linearity,which is suitable for measuring humidity of clasticdielectric on conveyer,is presented.With a microprocessor to sample and process the data,the accuracy isimproved.A dynamic experiment with this system was carried out on the conveyer at Shanghai CokingFactory and the results accord with variation regularity of the humidity of choice coal.
