The system utilizes a thermistor bridge for the measurement of temperature differences of ±2.5 C to an accuracy of ±0.025 C. Calibrations are shown for a range of ambient temperatures from 22 to 45 C. Equations are derived for calculation of the temperature difference from the observed meter deflection and constants which depend upon the characteristics and matching of the thermistors. A series of such measurements provide the data for derivation of thermal gradients.
