Microwave sensor and algorithm for moisture and density determination |
摘要 |
A microwave sensor and algorithm for instantaneous and nondestructive determination of bulk density and moisture content in granular or particulate materials at a single microwave frequency, especially agricultural commodities, which uses an inexpensive microwave circuit for determining the real and imaginary parts of relative complex permittivity using an algorithm for phase correction. |
