ABSTRACT:
An electronic apparatus to measure temperature which provides an accurate final temperature reading prior to the actual stabilization of the temperature sensor. An algorithm is provided which allows taking only two sensor temperature measurements at preselected times yet accurately predicts the sensor final or stabilization temperature. Temperature resistance varying signals are converted to temperature-frequency varying signals, clocked into an up/down counter, to compute final temperature which is displayed digitally. A thirty-second timing sequence is also digitally displayed for use when the invention is utilized for medical applications.
