How does the TCi thermal conductivity sensor work?
The TCi sensor generates heat at the surface. The tested object must be flat in order to evaluate thermal properties. When placed on the sensor, it absorbs some of this heat and the rest of the heat causes a temperature rise at the sensor interface. Insulation absorbs less heat than glass or from the TCi sensor’s reference, insulation leaves more heat behind than glass. The rate of temperature rise at the interface is evaluated to determine the thermal properties of the sample being tested.
