1. A thermocouple cable comprising a tubing and a plurality of thermocouple conductors bundled within the tubing, wherein each thermocouple conductor forms a separate junction with a shared thermocouple conductor to form a corresponding thermocouple junction, and forming a plurality of thermocouple junctions spaced apart from each other,
wherein each thermocouple junction of the plurality thermocouple junctions, includes the shared thermocouple conductor, and each thermocouple junction is attached to a common support cable inside a thermocouple bundle and the support cable is either the same or separate from the shared thermocouple conductor.
