    Abstract

    An analog fourth order polynomial curve fitting circuit was designed to linearize the thermocouple voltages of standard thermocouples. Typical design data and performance of the circuit is illustrated for the Type K thermocouple. This circuit can also be used to linearize the outputs of other types of transducers and simulate nonlinear variations with temperature of the physical quantities like absolute thermoelectric power of chromel and alumel.
