A new concept, called inductive noise thermometer, for measuring temperature of electrically conductive materials without any physical contact was realized in practice. In the method a low‐loss coil is placed close to the electrically conductive material. The increase in the noise voltage of the coil is related to the temperature of the material. Results from laboratory experiments on steel up to temperatures of 1300 K showed an agreement with conventional thermocouple recordings within an uncertainty of 1%. The thermometer built was also tested on a continuous casting machine of a steel mill. The preliminary experimental results were encouraging although at times external rf disturbances disrupted the measurement.
