FIELD: electrical engineering.
SUBSTANCE: device contains magnetically connected loops. The first loop, positioned close to the surface the temperature whereof is to be measured, is periodically adjusted, the period depending on the surface temperature. The second loop is positioned outside the voltage effect zone and connected to a pumping oscillator with an automatic frequency tuning system. Electric energy for the temperature sensor feeding and information on the surface temperature are transmitted by way of magnetic connection between the loops.
EFFECT: measurement accuracy increase, extension of the range of temperatures measurable.
