Abstract

727,228. Electric thermometers. GENERAL ELECTRIC CO. Nov. 9, 1953 [Nov. 12, 1952], No. 30967/53. Class 40 (1). An electric resistance thermometer comprising a coil of tungsten wire 4 wound on a grooved insulating former 5 and supported centrally inside a metal tube 1 with a packing of magnesia powder 15 has its thermal conductivity improved by the addition of a liquid 18 which soaks into the porous powdei and wets the tube 1 and the wire 4. The residual air in the tube is withdrawn through a glass tube 17 before the liquid 18 is added, and the tube 1 is then completely sealed, the leads being taken to terminals 9 via glass-metal seals 16. The liquid 18 must be non-corroding, have high chemical stability, good wetting ability, and good thermal conduc. tivity, e.g. Dow Corning 703 silicone fluid. The temperature - sensitive element may alternatively be a thermocouple.
