The object of study - the process of measuring temperature using redundant methods. The aim of the work is to increase the accuracy of measurements based on the methods of redundant measurements by processing the results of intermediate measurements on the equation of redundant measurements.
The conducted researches of possibilities of methods of redundant measurements established their high efficiency concerning increase of accuracy of measurements and possibility of maintenance of metrological self-control of temperature sensors. It is proved that the equation of redundant measurements ensures the independence of the measurement result from the parameters of the sensor conversion function and their deviations from the nominal values. The possibility of obtaining the equation of redundant measurements of the parameters of the sensor conversion function is also proved, which will allow the implementation of metrological self-control. Studies have confirmed that the accuracy of measurement is increased by processing the results of intermediate measurements on the equation of redundant measurements, in which due to the subtraction operation eliminates the additive component of error, and due to the division operation excludes multiplicative. It is established that the change of parameters of the transformation function under the action of external destabilizing factors by (1 ÷ 10)% does not affect the result of redundant measurements, ie the relative error in a given operating range will be δ1 = (0.040.01)%. This allows us to assert the conformity of the proposed mathematical model of the presented method to the results of computer modeling. On the basis of the offered mathematical models block diagrams of algorithms of work of redundant measurements, and also in the presence of a random component of an error are presented. The proposed algorithms are the basis for the development of appropriate technical solutions that implement the method of redundant measurement
