GAS FLOW TEMPERATURE GAGE Russian patent published in 2014 - IPC G01K7/02 G01K13/02 

FIELD: instrumentation.

SUBSTANCE: this device comprise thermocouple in metal case, its junction being located inside protective tip extending beyond said case. Thermocouple part extending beyond said case is composed by d-diameter metal tube terminated in flattened blade that makes the working thermal junction. Said metal tube features diameter decreasing towards said flattened blade that makes 0.4-0.5 d. said flattened blades has the following sizes: length - 0.3-0.4 d, width - 0.7-0.8 d, depth - 0.1-0.2 d. Said metal tube houses thermal conductors isolated one from another and from said tube changing over into flattened blade. Said conductors feature diameter decreasing proportionally with tube diameter and being constant inside said flattened blade. Said protective metal tip is perforated.

EFFECT: accelerated response, mechanical strength and resistance to gas dynamic loads of measured flow.
