Abstract

A sensor and method of manufacturing a variable resistance sensor with a protective sheath that is cost effective and highly reliable, with stable resistance with an operating range of up to 1700° C. in hostile environments. The sheath is formed of highly stable dispersion hardened materials capable of withstanding mechanical loads and chemical attacks at elevated temperatures while maintaining internal chemical integrity.

Claims (52)

1. A sensor comprising:

a resistor deposited on a substrate, said resistor exhibiting a change in resistance with a change in ambient temperature, said resistor comprising a noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

a first conductor formed from a first conductor material, said first conductor electrically connected to said resistor;

a second conductor formed from a second conductor material, said second conductor electrically connected to said resistor; and

a sheath enclosing at least said resistor, said sheath formed of a sheath material having at least one noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

said sheath being electrically insulated from said first and said second conductors.

2. The sensor of claim 1 wherein the first conductor material and the second conductor material are the same.

3. The sensor of claim 2 wherein the first conductor material and the second conductor material are different than the sheath material.

4. A sensor comprising:

a resistor exhibiting a change in resistance with a change in ambient temperature said resistor comprising a noble metal and an oxide selected from the group consisting of yttrium oxide, cerium oxide, zirconium oxide, and combinations of these;

a first conductor formed from a first conductor material, said first conductor electrically connected to said resistor;
