Abstract

Electrical analog modeling is the conventional way for the discussion of how thermoanalytical devices work. This tradition goes back to the 50–60s of the twentieth century, when the electric circuits worked with analog signal, and RC circuits were the advanced tool for the calculation of integrals and derivatives. Today the electric circuits work with digital signal, and the computation is performed with microchips and computers. Electrical analog modeling failed to explain how DSC calibration coefficient changes with temperature. This problem was solved by means of direct thermophysical consideration. The temperature of maximum sensitivity for three DSCs is shown to obey the equation for the calibration coefficient.
