ABSTRACT:
There is disclosed a telemetric temperature probe for telemetry of temperatures of comestibles which are heated within microwave ovens. The probe includes a temperature responsive circuit for generating a signal responsive to the temperature of the comestible and an electromagnetic wave broadcasting circuit for telemetric transmission of the signal to a remote receiver which can conveniently be incorporated in the microwave oven and coupled to its control circuit. The probe is provided with facilities to derive power necessary for its operation from the microwave energy generated by the oven and includes, for this purpose, an antenna to receive microwave energy, a rectifier circuit for developing direct current power therefrom and a voltage regulation circuit to produce a source of direct current of controlled voltage for operation of the temperature responsive circuit and the broadcasting circuit.
