    Channel-type distributed temperature sensing fiber

    DTSX measures temperature distribution over the length of an optical fiber cable using the fiber itself as the sensing element and it is ideal for temperature monitoring over long distances and wide areas. Distributed Temperature Sensing (DTS) systems provide temperature information for accurate thermal monitoring, fire detection, and condition assessment by utilizing standard fiber optic cables. These can have very high accuracies (0. 001 °C) and precision (+/− 0. Learn more about the ODISI for high-definition temperature measurement Strain sensors based on. Temperature is an interesting tracer that is used for many different hydrological and hydraulic measurements. DTS was developed in the petro-chemical industry to monitor for example oil.

  • Fiber Optic Voltage Sensing

    Fiber Optic Voltage Sensing

    Optical fibers can be used as sensors to measure, , and other quantities by modifying a fiber so that the quantity to be measured modulates the,,, or transit time of light in the fiber. Sensors that vary the intensity of light are the simplest, since only a simple source and detector are required. A particularly useful feature of intrinsic fiber-optic sensors is that they can, if required, provide distributed sensing over very large distances.
