Abstract
A method and apparatus for calibrating a Distributed Temperature Sensing (DTS) system. One or more discrete temperature sensors are positioned adjacent to a DTS fiber to calibrate data generated from DTS fiber. The discrete temperature sensors preferably comprise FBG (Fiber Bragg Grating) sensors.
Claims45
A cable comprising:
- a distributed temperature sensing fiber;
- and
- at least one calibration line for calibrating the distributed temperature sensing fiber, wherein the calibration line is coupled to at least one discrete calibration temperature sensor.
A system for calibrating a distributed temperature sensing fiber, comprising:
- a distributed temperature sensing fiber;
- at least one discrete calibration temperature sensor in proximity to the distributed temperature sensing fiber;
- and
- a calibration system configured to receive temperature data from the distributed temperature sensing fiber and the at least one discrete calibration temperature sensor, and calibrate the distributed temperature sensing fiber data using the discrete calibration temperature sensor data.

A method for calibrating a distributed temperature sensing fiber, comprising:
- receiving first temperature data from the distributed temperature sensing fiber;
- receiving second temperature data from at least one discrete calibration temperature sensor placed proximate to the distributed sensing fiber;
- and
- adjusting, if necessary, the first temperature data using the second temperature data.
