Silixa Ultima

Silixa ULTIMA is a family of temperature interrogators that pushes the boundaries of modern DTS (Distributed Temperature Sensing) technology. Using the advanced phenomenon of Raman scattering, the system transforms standard optical fiber into a dense network of thousands of measurement points, delivering a complete and continuous thermal profile in real time, with no dead zones.

Why choose the ULTIMA™ system?

Choosing the ULTIMA™ system is an investment in the highest data quality, which translates into safety and process optimization:

• Unmatched spatial resolution: The system enables measurements with a sampling interval as fine as 12.5 cm. This allows precise localization of pinpoint leaks or anomalies that, in standard systems (with 1–2 m resolution), would be averaged out and missed.

• Laboratory-grade thermal sensitivity: Thanks to advanced signal processing algorithms, ULTIMA™ achieves a temperature resolution on the order of 0.01°C. This sensitivity enables detection of the subtlest flow changes or early stages of exothermic processes.

• Measurement dynamics: The system offers exceptionally short integration times, allowing accurate temperature profiles to be generated in just a few seconds. This is crucial for monitoring rapid processes and emergency conditions.

• Stability and auto-calibration: Internal reference systems guarantee long-term measurement stability, minimizing the need for servicing and recalibration of the device in harsh field conditions.

Main applications:

1. Geotechnics and Water Engineering: Detecting leaks in dams, embankments, and flood levees by analyzing the temperature gradient.

2. Power and Industry: Monitoring the ampacity of high-voltage cables (RTTR) and detecting “hot spots” in process pipelines.

3. Oil & Gas and Geothermal: Precise temperature profiling in wells, production optimization, and reservoir integrity monitoring.

4. Environmental Research: Advanced monitoring of hydrological processes, river water temperature studies, and thermal monitoring of glaciers.

Advantage over standard systems:

Most DTS devices available on the market offer a spatial resolution limited to 1 meter. Silixa ULTIMA™ breaks this barrier, offering nearly ten times greater data density. In practice, this means that where other systems see a general trend, ULTIMA™ delivers a detailed picture, allowing preventive action to be taken much earlier and with greater confidence.
