Abstract
A high temperature sensor includes a pair of electrical conductors separated by a mass of electrical insulating material. The insulating material has a measurable resistivity within the sensor that changes in relation to the temperature of the insulating material within a high temperature range (1,000 to 2,000 K.). When required, the sensor can be encased within a ceramic protective coating.
Claims9
A high temperature sensor for monitoring changes in temperature within a range of 1000-2000.degree. K., comprising:
- first and second electrical conductors each having a melting point above the temperature range to be monitored;
- said conductors being within a length of metal oxide sheathed cable;
- and
- a mass of electrical insulating material separating the conductors, said mass of insulating material having a measurable resistivity change in relation to its temperature within the temperature range to be monitored.
