MEASURE OF THE THERMAL FLOW
Measurement, control, thermographic and infrared instruments
In building technology, the testing of the insulation capacity of building materials is an important topic of study. In addition to laboratory measurements of the thermal properties of materials, their behaviours is also studied through tests on field, in order to obtain information on the behaviours in different climates. The total heat flow through a material consists of a conductive, convective and radioactive part. In order to measure the heat transmission, a heat flow meter and some thermometers are used, assembled on both sides (interior and exterior) of a wall. After recording the flow and temperatures for a few hours, measured with high precision, the data is elaborated to obtain the average heat transmission of the wall.
