The role of the sensor signal amplifier in the electronic thermometer electrical circuit is considered. The operation of the amplifier discussed in the article was modeled using the MULTISIM program, and its characteristics were investigated on an experimentally manufactured sample. Experimental testing of the circuit showed the presence of amplified signal and quasi-linear dependence on temperature for the selected device configuration, particularly in the range of 35°C to 42°C where the signal varied from 1.126 V to 1.144 V. The need to eliminate circuit drawbacks and the influence of distortions and noise on obtaining a signal of the required quality were also discussed.

Regularities of the effect of elastic deformation on the energies of formation and activation of ions motion in superionic LaF3 crystals have been studied. It is shown that in the dielectric phase, when the distance…
Despite extensive research on perylene nanocrystal synthesis, the prenucleation processes are still poorly understood. Using reactive molecular dynamics simulations, we investigated these processes with flat perylene…
The macroporous silicon substrate was obtained through electrochemical etching and exhibited a uniform distribution of pores. For the deposition of the TiO2 film onto substrate, the thermal atomic layer deposition (ALD)…
The article presents a calculation of the angular distribution of the degree of polarization of diffusely reflected and transmitted natural solar radiation from atmospheric layers under multiple Rayleigh scattering. The…
The article considers the manifestation of the band structure of the electronic spectrum of non-metallic solids in a number of processes of the spin chemistry of radicals. It is shown that for a certain mutual…
The thermal desorption spectra of morphine, heroin, codeine, and papaverine have beenstudied at different temperatures TE of the surface ionization emitter. It was found that the dependence of the temperature of the…
Nickel oxide nanopowder was synthesized by the sol-gel method using nickel nitrate as the initial reagent. During the synthesis, the intensity of mixing of the initial mixture and the calcination temperature were…
In this paper, we study the question whether it is possible to explain the origin of all observed types of bulges of spiral galaxies on the basis of the mechanism of gravitational instabilities of vertical disturbance…
The growth of oxide layers of various dielectrics on the silicon surface is carried out at high temperatures (1150-1200) Celsius in an atmosphere of dry oxygen O2. The color of the coating is determined by its thickness…
In this work, we studied the change in the elemental and chemical composition of the Cu surface during cleaning by heating in combination with ion bombardment. For the elemental analysis of copper and the chemical…
