I Y Yankov, C I Gigov, E A Yankov · Measurement Science and Technology · 1990
A new approach for the linear conversion of temperature to time period using standard thermistors is described. The major advantages of the proposed converters are high sensitivity, simplicity and very good linearity. Analytical expressions for system performance are given and verified experimentally. A nonlinearity error of less than +or-0.002 K over a range of 10 K is obtained.
