ABSTRACT:
There is disclosed a fast responding temperature transducer circuit which provides an accurate steady-state output representing temperature in short periods of time. The circuit includes a temperature sensor which is sampled during alternate periods of time so that during one period, the temperature sensor provides a signal representing temperature, and during the alternate periods, the sensor output is shorted to prevent heat dissipation within the temperature sensor. The system may be used to achieve steady-state outputs in environments requiring fast response without a loss of accuracy and operable over wide temperature ranges.
