FIELD: measurement equipment.
SUBSTANCE: proposed method includes a stage of digital modelling of temperature measured by a sensor (10), with application of a modelled signal (T2), the stage of evaluation of a lag error signal (elag) for the specified sensor on the basis of the modelled signal (T2) and the signal (T3), produced by means of filtration of the modelled signal, and the stage of correction of the measurement signal (T1), issued by the sensor (10), by means of the evaluated signal of lag error. The filter as the parameter has evaluation of the time constant (τ) of the sensor. The time constant of the sensor is evaluated depending on the time from the measurement signal (T1) and the modelled signal (T2).
EFFECT: higher accuracy of correction of flow temperature in a turbojet engine of an aircraft.
