Product Description

Using optical fibers as the sensing medium, it is possible to remotely and real-time monitor the temperature of objects along the optical fiber route, which is a new technology for real-time measurement of spatial temperature field distribution. It can continuously measure the temperature along the optical fiber route, with a measurement distance of up to tens of kilometers, and has the advantages of high precision, non-electricity, resistance to RF and electromagnetic interference, fireproof, explosion-proof, corrosion resistance, high pressure and strong electromagnetic field resistance, radiation resistance, fast data transmission and reading speed, good self-adaptability, and precise positioning. It can work in various harsh environments and can be widely used in temperature monitoring and disaster warning in industrial sites such as offshore wind power, drilling platforms, power generation, petrochemical, transportation, metallurgy, etc.

Technical Principle

Distributed Temperature Sensing (DTS) detects the temperature changes at different positions along the optical fiber based on the temperature effect of optical time domain reflectometry (OTDR) and fiber Raman scattering, thus achieving truly distributed measurement.

In the system, optical fiber is both a transmission medium and a sensing medium. The temperature field at each point in the space where the optical fiber is located modulates the intensity of the Raman scattered light in the optic
