DIGITAL THERMOMETER Russian patent published in 2014 - IPC G01K7/32 

FIELD: measurement equipment.

SUBSTANCE: invention relates to thermometry and can be used for operation with temperature transducers with a pulse output signal. A digital thermometer includes a temperature transducer with a pulse output, a generator of rectangular pulses, a reversible counter with direct dynamic inputs, a parallel register with an inverse dynamic synchro input, AND element, NOR element, a code-frequency converter (CFC) and an additionally introduced ROM. A subtracting input of the reversible counter is connected to the output of AND element, the first input of which is connected to CFC output, the frequency input of which is connected to the output of generator of rectangular pulses, and the second input of AND element is connected to output of NOR element connected to the temperature transducer output. An adding input of the reversible counter with weight coefficient k is connected to the temperature transducer output and to the synchro input of the parallel register; outputs of the reversible counter are connected to inputs of the parallel register, the outputs of which are connected to CFC code inputs and inputs of ROM, the outputs of which are outputs of the device.

EFFECT: improving temperature measurement accuracy and enlarging functional capabilities of the device.
