DIGITAL THERMOMETRE Russian patent published in 2014 - IPC G01K7/32 G01K3/02 

FIELD: instrumentation.

SUBSTANCE: proposed device comprises thermal transducer with frequency output, square-pulse generator, up-down counter with direct dynamic inputs, parallel register with inverting dynamic sync input, code-frequency transducer (CFT) and extra permanent memory. Up-down counter subtracting input is connected with CFT output. CFT frequency input is connected with square-pulse generator while its adding input is connected to thermal transducer output and parallel register sync input. Up-down counter outputs are connected to parallel register inputs. Parallel register outputs are connected to CFT code inputs and permanent memory inputs. Permanent memory outputs make those of this device. This invention allows functional transform of pulse data by the use of frequency-pulse compensating servo system to allow continuous flawless generation of the result in compliance with temperature characteristic of thermal transducer.

EFFECT: higher precision.
