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.
