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. Key Words: Phase shift, moisture content, measurement, timber |
