SENSOR FOR MEASURING TEMPERATURE FIELD Russian patent published in 2017 - IPC G01K7/16 G01K11/00 

FIELD: measuring equipment.

SUBSTANCE: sensor for measuring the temperature field at the location space points of the elements of the single-use sensor for high temperature furnaces with a medium chemically inert to the sensor for measuring the temperature field is proposed. It consists of elements fixing the temperature in the space area where they are located and changes its state in the temperature heating process of the temperature field with the temperature from 600°C. Wherein the sensor for measuring the temperature field is made in the form of a flexible electroconductive filament based on carbon from polyoxadiazole, consisting of elements forming a single unit in the filament composition, changing its physico-chemical state under the action of a temperature field, fixing the maximum temperature of the temperature field from 600°C to 2300°C in the space area for determining the temperature field at points with coordinates along the filament location with the accuracy by length from 0.4 mcm.

EFFECT: increasing the temperature boundary for determining the temperature field due to the use of a flexible electroconductive filament based on carbon, obtained from polyoxadiazole, while simultaneously increasing the accuracy of measuring the temperature field in small volumes and hard-to-reach places due to the flexibility of the filament based on polyoxadiazole and the possibility of determining the temperature field at space points with the coordinates along the filament location.
