DIGITAL INTEGRAL THERMOMETER Russian patent published in 1995 - IPC

FIELD: environment thermometry. SUBSTANCE: thermometer has temperature detector, multichannel logic binary units amplifier-former, Gray code-binary code converter, binary adder, two memorizing units, timer, binary code-binary decimal code converter, indication unit. Sensitive element of temperature detector is made in form of two groups of bimetal spirals in three spirals in each group, mounted in parallel planes. Internal ends of spirals are fastened rigidly onto motionless axis inside which movable axis with disk are disposed. The disk is provided with annular code scale. Ends of three ancillary axes which are parallel to movable plane and passed through holes in the disk, are attached to external ends of corresponding bimetal spirals from any group being symmetrical relatively the disk. Code reading-out elements are located above code scale of the disk. Outputs of the elements have to be digital outputs of temperature detector. EFFECT: improved precision of measurement. 2 dwg
