Abstract :
A simple algorithm-oriented digital technique is described that utilises a truncated power series to linearise thermistor type sensor characteristics. Early truncation of the series, made possible by the adoption of a comparison algorithm, reduces the computation time considerably. The comparison algorithm also reduces the per cent full-scale deviation in nonlinearity to well within an acceptable limit. The software developed has flexibility in the selection of sensor specification and range
