Abstract:
A method and apparatus for determining the temperature of an environment at an elevated temperature (i. e. , one exceeding about 300. degree. C. ) wherein oxides that do not melt at such temperatures, do not age significantly at such temperatures and which have a sensitivity for such measurements are employed as thermistor resistors. Such oxides are calcium zirconate, yttria, alumina, dysprosia, magnesia, the oxide combinations alumina-silica, zirconia-silica and titania-silica. Measurements in electric current change is preferably the measurement of alternating current rather than the conventional dc current. A particularly useful instrument for such measurements consists of such a resistor with a laminate of connector metal such as diffusion bonded precious metal sheets or foils on separated surface areas as electrode connectors.
