BENDING TORQUE SENSOR WITH BUILT-IN TEMPERATURE SENSOR Russian patent published in 2023 - IPC G01F1/32 

FIELD: measurement instruments.

SUBSTANCE: bending torque sensor with a built-in temperature sensor consists of hollow cylindrical metal case 9, ending on one side with wedge-shaped wing 10, and on the other side with sealed inlet 11 with cables 12 connected to the piezoelectric assembly 13 and cables 14 protected by insulating rod 15 with temperature sensor 16 that can be installed on the lower surface of insulating rod 15, directly on the bottom of housing 9 or in a hole in the bottom of housing 9. The piezoelectric assembly consists of two parallel piezoelectric plates 18 metallized along the planes spaced apart in space, rigidly fixed to each other from the ends of the narrow faces with the help of clamps 19 made of a dielectric material, on one of the end surfaces of which grooves are made.

EFFECT: expanding the range of devices - bending torque sensors with a built-in temperature sensor, expanding the operational capabilities of the vortex flowmeter by enabling installation of a temperature sensor in it and enabling more accurate measurement of the flow rate in a relatively wide range.
