摘要:
A thermocouple linearizer circuit for use in a device for digitally displaying the temperature of a thermocouple. The circuit includes a plurality of proportional correction means, each connected to receive a non-linear electrical signal representing the temperature of a thermocouple. The correction circuits generate a correction signal proportional to the difference between a non-linear electrical signal and a predetermined reference signal. The correction signals are initiated when the non-linear signal exceeds the respective reference signal in each correction circuit. An arithmetic unit is included for adding the correction signals and the non-linear signal thereby forming a signal corresponding to a linear function of the temperature of the thermocouple.
