Executive Summary & Core Capabilities
The Yokogawa DTSX3000 is a flagship Distributed Temperature Sensor (DTS) built to protect critical infrastructure across vast operational distances. Traditional point sensors like thermocouples or RTDs leave dangerous unmonitored gaps and require thousands of individual signal cables. The DTSX3000 uses a single fiber line to measure temperature every 0.2 to 1 meter along distances up to 50 km.
Because optical fiber is completely passive and immune to electromagnetic interference (EMI), high voltages, and explosive gas atmospheres, the DTSX3000 provides total operational awareness in severe processing and transmission environments.
- 100% Linear Coverage: Replaces thousands of point thermal sensors with a single fiber cable, leaving zero blind spots.
- Immune to Severe EMI & Lightning: Operates safely inside high-voltage power conduits, subsea power lines, and transformer yards where copper wiring fails.
- 16-Channel Switching Capability: A single DTSX3000 unit can sequentially scan up to 16 separate optical fiber loops using an integrated optical switch.
- Extreme Temperature Resilience: Compatible with passive optical fibers capable of operating from cryogenic temperatures up to .
The DTSX3000 fires laser pulses down the fiber and evaluates Raman backscattering at two wavelengths: Anti-Stokes (temperature-sensitive) and Stokes (temperature-insensitive).
By calculating the intensity ratio relative to time delay , the unit determines exact local temperature at distance :
