AUTOMATION OF THE ITSM-1 INSTRUMENT FOR MEASURING THERMAL CONDUCTIVITY OF CONSTRUCTION MATERIALS
Annotation
Automation of commercially available thermal conductivity meter of construction materials ITSM-1 is carried out. The performed analysis of design of thermal unit of ITSM-1 make it possible to create an assembled electrical circuit of heat meters with a standard electrical resistor coupled with the AK-9.02 system of data collection and processing. Software for the conductivity meter calibration and measuring is developed as an application for ITSM-1 using Borland Delphi 7 for Windows. The instrument constant (thermal conductivity of the heat meters) is determined on the base of calibration with two standard samples of thermal conductivity made of LK-5 and Plexiglas.
