  • Patent number: 12596038
    Abstract: A system and method for calibrating a distributed temperature sensing (DTS) system having a fiber optic receiver coupled to an optical fiber, includes fiber Bragg gratings (FBGs) integrally formed within the optical fiber, and a processor configured to compute a temperature datum for a location of each FBG based on signals generated by the fiber optic receiver in response to light reflections from the FBG; and adjusting a computed temperature data profile along the optical fiber segment, based on the computed temperature datum for each location of an FBG.

  • Patent number: 12345152
    Abstract: A thermocouple cable is formed from a tubing and a plurality of thermocouple conductors bundled within the tubing, wherein each thermocouple conductor forms a junction with a shared thermocouple conductor to form a thermocouple junction, and each thermocouple junction is attached to a support cable in a thermocouple bundle. The cable is formed by pulling the thermocouple bundle into the tubing.
