Abstract
A photoelectric temperature controller is described which uses a thermocouple as the sensing element. The error signal operates a mirror galvanometer. The light from the galvanometer falls on a photocell and the photo-current is amplified by a differential D.C. amplifier operating a relay, which controls the furnace current. (Mr. K. Soma Kumar, Junior Research Fellow and Mr. A.P. Chowdhury, Senior Scientific Officer, National Metallurgical Laboratory)
