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...

The paper presents a new technical solution for the device of the primary sensing element of the MET sensor that stabilizes the temperature characteristics of the device due to the fact that the background current flowing through the cathodes of the converting element is controlled by a specially designed electronic circuit depending on the ambient temperature. In this case, a current is passed through the anodes, the value of which depends on the temperature according to a certain law. The cathode current value i...
