Distributed Temperature Sensing (DTS) utilizes multi-mode Fiber Optic cables to measure distributed temperature data. This generates a continuous temperature profile along the length of the cable. It is important to select the right team. Conventional measurement systems: usually based on electronic sensors. variation of refractive index, written into fiber core, using UV light. Raman: inelastic scattering, interaction with molecular vibration and rotation. Our SureVIEW™ Fiber Downhole Cable. Fibercore offers a range of designs for downhole fiber optic cable to meet the specific requirements of your oil or gas well.
