Distributed Temperature Sensing Market Growth & Trends

The global distributed temperature sensing market size is estimated to reach USD 1160.2 million by 2030, registering a CAGR of 8.4% from 2025 to 2030, according to a new report by Grand View Research, Inc.

In the Distributed Temperature Sensing (DTS) the optical fiber are used as a sensor. The operators can receive information related to temperature after installing such sensors in the fiber cable. The adoption of these sensors has increased rapidly in recent years due to their cost advantages. The DTS uses standard telecoms fiber, thereby requiring no special sensors, and thus saving cost. The cost of material, system design, installation, and maintenance are very low for these sensors, which in turn is projected to positively influence the market growth.

DTS offer fully distributed data, which minimized uncertainties and increased the amount of information received. In addition, these sensors offer very high reliability along with immunity to electromagnetic interference and shock/vibration. Also, distributed temperature sensing can be easily used in space-restricted areas. It also offer other advantages, such as high-temperature performance, long measuring ranges, high-temperature resolutions.

Various advantages of DTS contribute to its adoption across various industrial applications. Distributed temperature sensing is used for long length applications, such as in power cables, tunnels, and pipelines. The oil and gas segment hold majority of the market revenue share in 2024. The oil well industries are prominent customers, owing to its small size and easy accessibility of DTS. The safety and security segment is expected to register the fastest CAGR over the forecast period, due to substantial use of DTS in safety-critical applications where all points need to be monitored is also observed. These critical applications include electrochemical processes, LNG plants, and refineries.
