Royal Soc. 7 51 Hence, if in a circuit of copper and iron, one junction be kept about 280°, that is, at the neutral temperature, and the other at any lower temperature, a thermo-electric current will set from copper to iron through the hot, and from iron to copper through the cold junction. 1885 H. W. Watson & S. H. Burbury Math. Theory Electr. & Magn. I. 241 In an iron and copper couple this neutral temperature is, according to Sir W. Thomson, about 280°C. 1991 H. J. Gray & A. Isaacs Dict. Physics (ed. 3) 383/2 It is usual to restrict the use of a thermocouple to the range between 0 °C and its neutral temperature. < as lemmas |
