Abstract : The practical feasibility of developing a resistance thermometer, composed of an Ir resistance element mounted in Y2O3, for measuring temperatures in solids in the range 500 to 2000 C in an oxidizing environment was investigated. A sensor design was evolved that embodies a flat grid of 10 inches of 3-mil Ir wire with 10-mil Ir leads. This sensing element is cast in Y2O3 under pressure, and the sensor is consolidated by high-temperature sintering. It was concluded that a resistance thermometer of Ir mounted in Y2O3 is feasible to at least 1400 C. It is probable that the range can be extended to 2000 C by improving controls on the purity of the oxides used with the Ir wire. Recommendations are made for continued development and testing.
