Abstract
The temperature of an object within a heating furnace is accurately measured, even in a contaminated atmosphere, by receiving microwaves within a specific 1 to 10 cm wavelength range by means of an antenna provided near the wall of the furnace facing the surface of the object to be measured. The temperature of the object is obtained by amplifying, and converting the relative intensity of the microwaves. The antenna is preferably in the form of a parabolic antenna having a heat insulating material applied to its front surface to maintain a constant temperature, and a circuit added to compensate for any sensitivity fluctuation due to temperature changes in the parabolic antenna.
