Portable system RTP and itís application
An instrument RTP was constructed to realize the measurements, to calculate the required parameters and to store the corresponding data. The instrument consists of the hot ball sensor and the electronic unit that realizes the required functionalities to obtain data on thermal conductivity and the data logger. The measurements are performed in the measuring cycles. A cycle consists of measuring a ball temperature (base line), generation of a constant heat in the ball, measuring the temperature response of the ball (see plot below). The heat generation is interrupted after some time when the temperature is stabilized. Then a period of the temperature equilibration follows.
