ABSTRACT:
A radiation detector comprises a thermopile and a thermocouple connected in series. The cold junction of the thermocouple is connected to a remote temperature reference. A calibrator in the thermopile/thermocouple circuit weights the output signals of the two devices to provide a combined output signal which changes with both sensed radiation and ambient temperature. The device may be calibrated for an environmental control system to control heating or cooling based on both air temperature and radiant temperature of surrounding surfaces. In another application, the thermocouple and calibrator provide a simple signal adjustment to provide an internal temperature reading from a sensed surface temperature. For example, the circuit can provide a core temperature reading from detected ear temperature.
