ACCURACY ANALYSIS OF NON-DESTRUCTIVE MEASUREMENT METHODS IN CONTROL OFFROZEN WOOD MOISTURE CONTENT
(pp. 45-52)

Abstract. The work is devoted to measuring the accuracy of wood moisture content measurement by conductometric and inductive (non-contact) additional non-destructive methods, as well as their comparison with the standard drying-weight method. The novelty and practical significance of the results are associated with studies of the accuracy of methods in measuring frozen wood. The work defines random components of error and the total error of measuring wood moisture content at normal temperature and in a frozen state by non-destructive measurement methods. It is equal to 3 %. Relative error of measurements by conductometric and inductive measuring devices are determined. Analysis of the obtained results showed that the accuracy of non-destructive methods is the same and is ensured when measuring wood with a moisture content of up to 22 %. It was found that the frozen state of wood does not have a significant effect on the accuracy of these methods when determining wood moisture content. Therefore, conductometric and inductive measurement methods can be used when determining moisture content, in particular, of frozen wood.

Keywords: accuracy of wood moisture content measurement, conductometric method, frozen wood, inductive method, measurement error.
