Apparatus and method for the simultaneous measurement of rheological and thermal characteristics of materials and measuring cell therefor

摘要

The appts includes a heat flux device juxtaposed with at least a first platen for changing a temp of a test specimen. A body of heat conductive material is integrated with the first platen and interposed between the heat flux device and the test specimen so as to conduct heat between the heat flux device and the test specimen with a minimum of resistance to the conduct of heat through the body. A first temp detector is used for detecting the temp of the body of heat conductive material. A second temp detector is provided for detecting the temp of the test specimen. The second temp detector is placed at a location adjacent the body of heat conductive material and thermal resistance device between the body of heat conductive material and the location of the second temp detector. Such arrangement is used for resisting thermal conductivity between the body of heat conductive material and the second temperature detector.
