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 introduced into production practice significantly reduce the operating time of the device setup (long-term and expensive temperature measurements and verification in thermal cameras are no longer required), respectively reducing the production cost. Most importantly, the proposed method significantly improves the quality of temperature compensation due to the automated selection of individual ratings, which reduces the spread of sensitivity parameters from device to device and its stability at the temperature range edges.
