With all the benefits of the LIOS PRE.VENT, but with an even longer measuring range, the LIOS PRE.VENT Long Range offers users a unique chance to monitor very large structures with just one installation.
The solutions provides highly reliable and exact data – even in industrial environments – while providing robustness, scalability, and an option to have up to 16 individual channels enabling the coverage of complex infrastructure. Even in large and complex installations the LIOS PRE.VENT Long Range still provides a cost-effective and yet fully automated data analysis with a very precise and accurate temperature mapping.
Using only a single optical fiber, our DTS system covers thousands of measuring points along the sensor cable making the DTS technology far more efficient in installation and maintenance cost compared to other sensor technologies.
The fiber can withstand very high temperatures, mechanical and environmental exposures and can therefore be used for a very large variety of applications where extreme heat is a challenge such as induction furnaces or chemical reactors.
At NKT Photonics, we are strong in design engineering and we turn complex and customized solutions with different cable designs into simple turn-key solutions delivering reliable cost-effective temperature monitoring solutions.
Mean Time Between Failures of 40+ years
Reliability is critical when it comes to DTS systems. With 5,000 DTS systems in operation, we have calculated a remarkable MTBF of 40+ years.
Made from Telcordia rated components, passive cooling and no moving parts, our DTS systems are basically maintenance-free. The self-diagnosing features free you from worrying and allow you to focus on other important tasks.
