The first conductor is constructed of a first material and the second conductor is constructed of a second material that is different than the second material. The second temperature sensor has third and fourth conductors extending within the interior space of the sheath and joined at a second junction point. The third conductor is constructed of a third material and the fourth conductor is constructed of a fourth material that is different than the fourth material. The first material is different than each of the third and fourth materials. The first junction point is adjacent to the second junction point.

Abstract

In one aspect, a temperature sensing assembly for measuring temperature of a surface of a structure includes a thermocouple device and a docking device. The thermocouple device includes a temperature sensing junction point disposed within an elongate sheath to measure the temperature of the surface of the structure at a desired location. The thermocouple device further comprises a contact portion configured to contact the surface of the structure. The docking device has a bottom surface to attach to the surface of the structure adjacent the desired location. A line extends through the center of the sheath and the sheath has a cross-sectional area in a plane perpendicular to the line. The contact portion is configured such that, when the docking device is coupled to the surface, an area of contact between the contact portion and the surface of the structure is greater than the cross-sectional area of the sheath.
