APPARATUS MEASURING TEMPERATURE Russian patent published in 2002 - IPC

FIELD: measurement technology. SUBSTANCE: apparatus includes thermal resistance converter with three communication lines, measurement amplifier, current former switching on operational amplifier with current-setting resistor and power supply source, zero setting resistor. Apparatus is supplemented with code controller, digital-to-analog converter and adder connected in series. Another input of adder is connected to output of measurement amplifier. Zero setting resistor is placed between one communication line and inverting input of operational amplifier in current former. Effect of resistance of communication lines is corrected by insertion of compensating code. EFFECT: expanded functional potential, raised adaptability to manufacture and operational properties of apparatus. 1 dwg
