Abstract

A small sensor for the dynamic measurement of local moisture content within a wooden member exposed to fire heating is developed. The measurement is based on the unique dependence of electric resistance of wood on moisture content and temperature. Relationship between those is obtained by experiments for temperature between 20°C and 90°C, and moisture content between 6.9% and 232.8% for Cryptomeria japonica, Larix leptolepis, Pseudotsuga menziesii and Zelkova serrata. Electric resistance is represented with temperature and moisture content for each tree species. The measurement is found to be most effective within the moisture content 10%. 30%.
