HEAT RECEIVER Russian patent published in 2023 - IPC G01K7/02 

FIELD: measuring technology; temperature sensors.

SUBSTANCE: heat receiver contains a heat-receiving element with two thermocouples, an insulating sleeve, an output electrical cable with a fixing nut and washer, and the thermocouple leads pass through the insulating sleeve, fixing the washer and nut, the output cable and are connected to the output electrical connector; a thin-walled heat-resistant cap is inserted into the heat-receiving element at the end, connected over the entire surface of the internal sample of the cap with the mating outer surface of the heat-receiving element using compression welding, the internal volume of the heat-receiving element is filled with a material with a low thermal conductivity coefficient, and the thermocouples are made in a heat-resistant design.

EFFECT: expansion of the dynamic range of measurements of heat flows with high power, dynamics and pressure, as well as an increase in the service life of the sensor when used in gas pipelines, starting with their minimum diameters.
