Your Questions About DTSX3000 Series — Answered
DTS uses laser light in optical fibers to detect temperature changes at every meter over long distances. It transforms a single cable into a continuous temperature sensor.
Its ability to monitor wide temperature ranges (-220°C to +800°C) with extreme precision (0.03°C resolution), while covering long distances (up to 10 km), makes it ideal for mission-critical sensing tasks.
It uses 50/125µm graded-index fibers with E2000/APC connectors, making it compatible with common fiber installations.
The DTSX3000 works like a long-range digital thermometer that uses a fiber optic cable instead of individual temperature sensors. This fiber runs along pipelines, tunnels, power cables, or other critical infrastructure. The device constantly monitors temperature changes along the entire length of the fiber — often stretching for several kilometers.
Instead of placing hundreds of separate sensors, the DTSX3000 can detect small shifts in heat at any point along the cable. This helps engineers quickly locate things like fluid leaks, electrical faults, or hotspots before they become serious problems. It’s a powerful tool for keeping large systems safe, efficient, and easy to monitor — all from a single device.
