Abstract : The patent describes a device to measure the intensity of an electromagnetic field. A thermocouple is connected to a meter and placed adjacent a small resistance in a line carrying current induced by the electromagnetic field. This current produces heat in the resistor which is sensed and converted into a DC voltage by the thermocouple. This DC voltage causes the meter to indicate the intensity of the electromagnetic field. To prevent error due to electromagnetically coupled energy heating the thermocouple and/or producing a high frequency current which is conducted to the meter circuit from interfering with the meter readings, a physically small thermocouple with semiconductor leads or a semiconductor thermocouple having semiconductor leads is provided.
