Temperature-measuring device
First Claim
1. A temperature-measuring device comprising:
- an elongated housing having a closed end;
a body of refractory material in said housing;
a noise-thermometer coil in said housing adjacent said closed end and having a pair of opposite extremities;
a pair of spaced-apart thermocouple elements extending through said body and each forming a thermocouple junction with said noise-thermometer coil at a respective extremity thereof, said elements being of materials which are capable of forming a temperature-measuring thermocouple junction with one another; and
two pairs of pair of conductors, each conductor being connected to one of said elements remote from the junctions thereof with said extremities and leading from said housing.

Abstract
A temperature-measuring device has an elongated tubular housing in one of ose closed ends is received a noise-temperature resistor having at least one side connected via a wire constituting a thermocouple element to a lead connected to temperature-measuring apparatus. The other side of the noise-temperature resistor is connected to the tubular housing which therefore constitutes the other element within the housing and connected via leads to apparatus without the housing. The thermocouple element or elements may extend from the noise-temperature resistor outside the housing, or may be wholly contained within the housing and connected via a pair of leads to apparatus outside the housing.
