Simulation Modelling of Results of Measuring Surface Temperature Under Electric Voltage

Based on the concept of concentrated capacity and method of thermally thin layer the mathematical model of heat transfer in the system of metal frame-paraffin is created. The reduction of the mathematical model is made, the calculated formula for implementation in microcontroller of smart sensor of temperature for inaccessible surface (SS TIS) is obtained. On base of simulation modeling of measurement information with use of explicit solution of model problem it is became obvious that the absolute error of the surface temperature measurement under electric voltage can be reduced up to 1 °C.
