Abstract
A new induction heated fixed-point device for calibration of temperature measurement devices, typically used in laser heat treatment for the temperature range between 1000 °C and 1500 °C, was developed. To define the requirements for the calibration method, selected measurement set-ups were compared and process data and results of industrial processes were analyzed. Computer simulation with FEM and FDM was used to optimize the system components and processing parameters of the induction heating of fixed-point cells. The prototype of the fixed-point device was tested successfully and first measuring results are shown. The new calibration method is expected to improve the quality and reproducibility of industrial heat treatment processes with temperature control.
