Distributed Temperature Sensing Market Poised for Growth in Utilities Sector

The global distributed temperature sensing (DTS) market size was estimated at USD 710.4 million in 2024 and is projected to reach USD 1,160.2 million by 2030, growing at a CAGR of 8.4% from 2025 to 2030. The growth of this market is primarily attributed to the increasing adoption of DTS technology across diverse application industries, including oil & gas, environmental monitoring, fire detection, and more.

A growing emphasis on worker safety has further fueled the demand for DTS systems. These systems offer precise and real-time temperature monitoring, making them essential in environments where safety and operational efficiency are paramount.

In the oil & gas sector, DTS technology is widely utilized in petrochemical facilities, pipeline infrastructure, drilling operations, and storage tanks for accurate thermal profiling and temperature measurement. The technology’s high performance in extreme and hazardous environments, along with its resistance to electromagnetic interference, positions it as a preferred choice for upstream oil and gas operations, particularly for remote monitoring of offshore wells.

In the power and utility sectors, ensuring the safety and reliability of high-voltage transmission networks is critical. DTS systems equipped with advanced optical fibers play a vital role in achieving continuous and accurate temperature monitoring. While multimode fibers are used for medium-range applications, single-mode fibers are favored for long-distance coverage of up to 60 kilometers. Additionally, DTS is gaining traction in civil engineering for applications such as groundwater flow measurement, subsurface heat transport, environmental monitoring, and heat flux analysis.
