FIELD: physics.
SUBSTANCE: invention relates to physical measurements, particularly to methods of controlling sensors with series-connected electric heaters of two spaced apart sensitive parts. Method consists in that supply voltage is periodically supplied to electric heaters of the first and the second identical sensitive parts with a small time delay on each measurement cycle. Thermal state of the sensitive parts is recorded and compared. At each measurement cycle the supply sequence of supply voltage of electric heaters from sequence "first-second" to "second-first" sequence and vice versa is changed.
EFFECT: reduced measurement error.
