title: New method for moisture content measurement using phase shifts at two microwave frequencies.
abstract: A new method to measure moisture content of material is described in this paper. The method is based on two phase shifts of transmitted microwave signal at two different frequencies. The result using this method for moisture measurement of timber indicates this method being effective. The maximum error and mean value of error in moisture range from 2 to 30% on dry basis are 4.1% and 1.9%, respectively.
