摘要：

Dimensional change of building materials as a function of temperature and moisture is important characteristic that needs to be monitored. In cooperation of the Department of Physics at STU and company METRODAT the dilatometer for measurement of thermal and moisture expansion coefficient was produced. Measuring systems using LVDT sensor located into ZERODUR closed loop measurement frame provide the maximum precision, repeatability and accuracy in temperature range from -15 degrees C to 105 degrees C and from 10 % to 100 % relative air humidity. The sample holder is made from stainless steel and allows to work with samples from 10 mm to 160 mm of initial lengths. The measurement process is PC controlled.
