Yokogawas DTSX3000 is an advanced distributed temperature measurement solution that uses fibre optic technology to measure temperatures along the entire length of the cable. This technology enables real-time temperature monitoring over long distances, making it ideal for applications that require continuous temperature monitoring and early detection of changes.
How is temperature measured?
The DTSX3000 uses optical reflection to measure temperatures along fibre optic cables. The technology makes it possible to obtain measurement data with millimetre precision, ensuring reliable and accurate temperature measurements even in challenging environments. With support for both single and double end measurement, the system can be used for redundancy in critical applications, making it possible to ensure operational reliability even in difficult conditions.
Advantages of the DTSX3000:
- High precision: Measurements with millimetre resolution over long distances.
- Real-time monitoring: Direct feedback to identify temperature variations and potential risks.
- Flexible installation: Long measuring distance and possibilities for both single and double end measurement.
- Energy efficient: Low power consumption makes it durable for long-term use.
Areas of use:
- Fire safety: Early warning of fires in industrial plants, tunnels and warehouses.
- Pipeline monitoring: Detection of leaks and flow anomalies in pipelines, especially in oil and gas.
- Power plants and energy distribution: Monitoring of cables, transformers and electrical systems to prevent overheating.
- Infrastructure monitoring: Temperature monitoring in buildings and structures to detect structural problems.
