DIGITAL THERMOMETER Russian patent published in 1994 - IPC

FIELD: digital systems of collecting meteorologic information. SUBSTANCE: temperature sensor has a temperature-sensitive element made in the form of three bimetallic spirals mounted in parallel planes, multichannel digital signal processing unit to which digit outputs of the temperature sensor are connected. Inner ends of bimetallic spirals are fixed to a stationary axle within which a movable axle is located. Outer ends of bimetallic spirals are rigidly connected to the ends of three auxiliary identical axles which second ends are secured to the movable axle at an angle of 90 degrees. The temperature sensor furthermore has code reading elements disposed over a disk with circular code scale which is mounted on the movable axle. EFFECT: enhanced accuracy. 4 dwg
