Abstract
In this paper, a measurement system is designed to deal with the problem of measurement of the coal moisture content. Based on the measurement principle including standing-wave ratio and permittivity, develop the whole measurement system from the hardware and software aspects. The measurement system of coal moisture content based on standing-wave ratio has the advantages of less measuring time, higher accuracy and larger measurement range according to the results. And it can apply in the coal moisture content measurement in many industry fields.
