ABSTRACT:
A highly accurate low-cost electronic thermometer with digital readout, intended primarily for clinical use. Temperature sensing is accomplished by a thermistor in a probe assembly which includes a unique disposable probe cover which provides excellent thermal contact with the thermistor to a measuring circuit which includes a bridge and a rebalancing servo. Digital readout is accomplished by a coding disc driven by the servo and pickoff brushes. The coding pattern on the disc provides analog to digital conversion, compensation for the inherent nonlinearities of the thermistor, and a nonvolatile memory. Means are provided for operating the thermometer in an estimation mode to give readings more quickly than would be otherwise permitted by the thermal response of the probe. In estimation mode, measurement is terminated at a predetermined point in the measurement cycle, and a special calibration of the measurement circuit is used to give an estimate of what the final temperature would be.
