In this paper, we propose a mathematical model and an appropriate algorithm that allows one-time measurement of the frequency response and phase response of the MET sensor under normal conditions to construct a complex transfer function of the MET at any other temperatures from the allowable range of -35 + 55 °C with the experimental accuracy not worse than a few percent. This model and the algorithm for setting up and selecting thermocompression circuits of electronic amplification and filtration circuits introdu...
