Abstract
A temperature sensor includes a pair of thermocouple wires, a temperature measuring junction formed by joining tip ends of the pair of thermocouple wires together, an outer tube having a tip end provided with a tip end cover in which the temperature measuring junction is held, an insulator insulating the pair of thermocouple wires from the outer tube, and a glass seal filled in a base end of the outer tube to seal the outer tube from inside thereof. The glass seal contains bubbles which are independent of each other.
Claims8
A temperature sensor comprising:
- a pair of thermocouple wires made of respective metallic materials different from each other;
- a temperature measuring junction formed by joining tip ends of the pair of thermocouple wires together;
- an outer tube made of a metallic material and having a tip end and a base end, the tip end holding the temperature measuring junction therein or having a tip end cover mounted thereto in which the temperature measuring junction is held, the base end allowing the pair of thermocouple wires to protrude therefrom;
- an insulator made of an insulating material and disposed in the outer tube to insulate the pair of thermocouple wires from the outer tube and fix the pair of thermocouple wires to the outer tube;
- or
- a glass seal made of a glass material and filled in at least either of the base end of the outer tube and a holder mounted to the base end of the outer tube to seal the outer tube, wherein
- the glass seal contains bubbles which are independent of each other.
