DTS1000 Long-Range Fiber Optic Temperature Sensor (20 km)

DTS-4C-20KM

The DTS-4C-20KM Distributed Optical Fiber Temperature Sensing System is a high-performance solution for continuous, real-time temperature monitoring over long distances up to 20 km. Using Raman scattering and OTDR (Optical Time Domain Reflectometry) technology, the optical fiber itself acts as a linear temperature sensor, enabling precise hotspot detection, accurate location identification, and early fire warning. It is ideal for critical infrastructure and industrial safety applications.

Covers long distances up to 20 km with continuous monitoring
Detects hotspots with high precision (1-meter resolution)
Early fire detection and preventive safety
No multiple sensors required → single fiber covers entire asset
Reliable in harsh and hazardous environments
