Preliminary Exploration of On-Line Measuring Layer Moisture Content with Electrical Resistance Method during Wood Drying

Abstract:

Article Preview

Electrical resistance method was used to detect layer moisture content across the thickness of Larch (Larix gmelinii) specimen during drying, and the temperature of the same layers and the environment were also measured by remote temperature scanner. During the drying process, layer moisture content was obtained from other Larch specimens with slicing method. Layer moisture content measured with electrical method was compared with that acquired with slicing method. Results showed that the wood center temperature was more suitable than the environment temperature as compensated temperature to amend moisture content measuring with electrical resistance method; variation of layer moisture content of Larch specimen could be more or less measured with electrical resistance method, and had a relatively good agreement with that acquired with slicing method except that u15 was 3% higher than U1 and u3 was 4% higher than U3 in the middle stage of drying.
