Mechanical Temperature Measuring devices Principle of Operation A change in temperature causes some kind of mechanical motion, typically due to the fact that most materials expand with a rise in temperature. The purpose of this paper is to analyze the existing methods for selection of measuring equipment. Measuring Instruments. We develop and produce electrochemical measuring cells and analysis software. Laser measure tools are used to measure the distance between itself and an object.
