Abstract
A temperature sensor includes a block body, a first thermocouple, and a second thermocouple. The first thermocouple includes a first strand, a second strand, a first insulator surrounding the first strand and the second strand, and a first metal sheath surrounding the first insulator. The second thermocouple includes a third strand, a fourth strand, a second insulator surrounding the third strand and the fourth strand, and a second metal sheath surrounding the second insulator. An end portion of each of the first thermocouple and the second thermocouple is buried in the block body.
