FIELD: physics.
SUBSTANCE: temperature measuring transducer with a metrological accuracy controller has a thermo-resistive sensitive element made of parts with different sensitivity to the factor influencing metrological accuracy of the temperature measuring transducer, and a measurement and control unit, the inputs of which are connected to corresponding parts of the sensitive element. One of the parts of the sensitive element is made from several, preferably two, conductors connected in parallel. Total cross-sectional area values of the parts of the sensitive elements are comparable to each other.
EFFECT: high accuracy of correcting temperature measurement results directly during operation and possibility of increasing the calibration interval.
