DTS & DAS Solution Page

DTS & DAS Solution

"DTS" stands for Distributed Temperature Sensing, and "DAS" stands for Distributed Acoustic Sensing. Both technologies use optical fibers to monitor environmental data in real-time. While they share the ability to collect continuous data over long distances, the type of information they gather and their applications are different.

DTS (Distributed Temperature Sensing)

DTS is a technology used to measure temperature along an optical fiber. It operates based on the Raman scattering effect. When a laser beam is transmitted through an optical fiber, a portion of it is scattered and returns. By analyzing the intensity and time delay of the scattered signal, the temperature at each point along the fiber can be measured.

  • 01

    Continuous Temperature Measurement

    DTS can measure temperature with high spatial resolution along the entire length of the optical fiber.

  • 02

    Long-Distance Measurement

    A single sensor cable can detect temperature changes over tens of kilometers.

  • 03

    Real-Time Monitoring

    DTS provides real-time temperature data, allowing for quick detection of environmental changes.

Main Applications Image

  • 01

    Oil & Gas Pipelines

    Detect temperature variations to identify leaks or defects in pipelines early.

  • 02

    Fire Detection

    Rapidly detect fires in tunnels, industrial plants, and equipment.

  • 03

    Geothermal Energy

    Monitor temperature changes in geothermal reservoirs in real-time.

DAS (Distributed Acoustic Sensing)

DAS is a technology used to measure acoustic vibrations along an optical fiber. It utilizes the Rayleigh scattering effect, detecting vibrations or sounds that occur along the fiber and analyzing them. Vibrations cause tiny changes in the curvature of the fiber, which are optically detected to gather sound or vibration information.

  • 02

    Long-Distance Monitoring

    Acoustic and vibration data can be collected over tens of kilometers.

  • 03

    Real-Time Data

    It can detect vibrations or abnormal events in real-time, enabling immediate response.

Main Applications Image

  • 01

    Pipeline Monitoring

    Detect leaks, damage, or unusual operational activities in pipelines.

  • 02

    Railway Monitoring

    Track train movement, detect track defects, and monitor train positions.

  • 03

    Security Systems

    Used for intrusion detection, tunnel monitoring, and environmental surveillance.

Differences between DTS and DAS

Both solutions leverage the sensitive detection capabilities of optical fibers, making them valuable technologies for real-time monitoring of large-scale facilities or infrastructures.

Differences between DTS and DAS Image

  • 01

    Measurement Target

    DTS primarily measures temperature changes, while DAS detects vibrations and acoustic signals.

  • 02

    Application Scope

    DTS is used in industries where temperature monitoring is crucial (e.g., geothermal energy, pipeline leak detection), whereas DAS is widely used in industries requiring vibration and sound detection (e.g., security, railways).
