ABSTRACT:
A metal surface temperature monitor is disclosed. The monitor comprises a rotating sensor head including two wheels fabricated from thermocouple materials and adapted to ride on the surface of the metal to measure the temperature thereof, a converter for converting the thermal EMF generated by the thermocouple to a low frequency coded signal, a transformer having a stationary primary winding and a secondary winding which is free to rotate with the sensor head, a modulating circuit associated with the primary and secondary windings of the transformer for transferring the frequency coded signal from the secondary to the primary winding of the transformer, and means connected to the primary winding of the transformer for demodulating the frequency coded signal to provide an indication of the temperature of the moving metal surface.
