Yokogawa DTSX Series Distributed Temperature Sensor

2025-03-16

In the fields of industrial safety monitoring and energy management, Distributed Temperature Sensing (DTS) technology has become a critical tool for accident prevention and process optimization, thanks to its long-distance, high-precision real-time temperature monitoring capabilities. Yokogawa’s DTSX Series Distributed Temperature Sensors are widely adopted in oil and gas, power transmission, tunnel fire protection, and other scenarios due to their exceptional reliability, adaptability, and intelligent analytics. This article explores the core technologies, popular models, and industry-specific solutions of the DTSX Series, empowering enterprises to achieve end-to-end temperature visibility and control.

I. DTSX Series Overview and Technical Highlights

Yokogawa’s DTSX Series leverages Raman Optical Time Domain Reflectometry (ROTDR) to enable continuous temperature monitoring over distances up to 30 kilometers, with a spatial resolution of 1 meter and temperature accuracy of ±1°C. Key advantages include:

· Full Distributed Monitoring: A single fiber replaces traditional point sensors, reducing deployment costs.

· Robust Design: Resistant to extreme temperatures (-40°C to +300°C) and electromagnetic interference, ideal for harsh environments like refineries and substations.

· Smart Diagnostics: Built-in AI algorithms automatically identify hotspots, abnormal temperature gradients, and trigger alerts, with seamless integration into SCADA and DCS systems.

Popular Models

1.DTSX3000

Applications: Pipeline leak detection, storage tank fire prevention.

Features: 50 km maximum range, ATEX/IECEx certification for Class I/II hazardous areas.

2.DTSX200

Applications: High-voltage cable monitoring, substation busbar overheating detection.

Features: 0.1°C temperature resolution, multi-channel switching (up to 8 channels) for complex power grids.

3.DTSX Compact

Applications: Urban utility tunnels, subway fire safety monitoring.

Features: Lightweight, IP67-rated design for rapid deployment in confined spaces.

II. Industry Solutions and Success Stories

1. Oil & Gas: Long-Distance Pipeline Safety

In a Middle Eastern oil pipeline project, the DTSX3000 detected a 0.8°C temperature anomaly caused by corrosion, preventing environmental damage and reducing annual maintenance costs by 35%.

2. Power Industry: Dynamic Cable Load Management

A European grid operator used the DTSX200 to monitor high-voltage cable temperatures, dynamically adjusting transmission capacity to boost utilization by 20% and extend equipment lifespan by 3-5 years.

3. Smart Cities: Underground Utility Tunnel Fire Prevention

In a Chinese urban tunnel, the DTSX Compact detected temperature spikes (e.g., cable overloads or gas leaks), triggering fire suppression systems within 10 seconds.

III. Competitive Advantages of the DTSX Series

1. Cost Efficiency: Up to 50%-70% lower total cost than traditional point-sensor solutions.

2. Scalability: Modular design supports customizable channels and communication protocols (Modbus TCP, OPC UA).

3. Data Integration: Compatible with Yokogawa’s IoT platform GA10 for multi-parameter analysis (temperature, vibration, pressure).
