DIGITAL INTEGRAL THERMOMETER Russian patent published in 1994 - IPC

FIELD: meteorological information acquisition systems. SUBSTANCE: thermometer has a temperature sensor, amplifier-shaper of logic binary unities, Grey code-to-binary code converter, binary adder, two storage devices, timer, binary-to-binary-decimal code converter, indicator. A temperature sensor sensitive element is made in the form of three bimetallic spirals mounted in parallel planes. The inner ends of spirals are rigidly coupled with a stationary axle within which a movable axle with a disk with a circular code scale secured to it are disposed. The outer ends of spirals are rigidly coupled with the ends of identical auxiliary axles the other ends of which are fixed to the movable axle at an angle of 90 degrees. Furthermore, there are code-reading elements over the code scale. EFFECT: enhanced accuracy. 5 dwg
