Coaxial thermocouple sensor

A temperature sensor, comprising:

• a first wire assembly having a first metallic conductor and a first insulator at least partially enclosing said first metallic conductor, said first wire assembly having a first uninsulated segment at which a portion of said first metallic conductor is free of said first insulator;
• a metallic jacket at least partially coaxially enclosing said first wire assembly, said metallic jacket being positioned in direct physical contact with said first metallic conductor at said first uninsulated segment whereby a measuring junction is formed;
• a carrier wire assembly having a second metallic conductor and a second insulator at least partially enclosing said second metallic conductor, said second wire assembly having a second uninsulated segment at which a portion of said second metallic conductor is free of said second insulator,
• wherein said metallic jacket is also positioned in direct physical contact with said second metallic conductor at said second uninsulated segment, and
• wherein said second uninsulated portion of said carrier wire assembly is located at a distal end portion of said second wire assembly.

Temperature sensor incorporating a bi-metal thermocouple, comprising:

• a first metallic wire having an uninsulated portion and an insulated portion;
• a metallic jacket at least partially coaxially enclosing said first metallic wire, said jacket being directly in electrical contact with said uninsulated portion of said first metallic wire to thereby form a measuring junction;
• an electrically insulated carrier wire provided with a blank uninsulated portion;
• said jacket and said carrier wire consisting of the same metallic material, and said jacket further enclosing said carrier wire at least in the region of said blank uninsulated portion of said carrier wire, thereby being directly in electrical contact with said blank uninsulated portion of said carrier wire, and
• said jacket extends on said carrier wire over said blank uninsulated portion thereof and further over an adjacent portion thereof.
