Our approach to your special needs – Explore more

The LIOS’ DTS technology has been successfully proven in critical applications like fire detection in road and rail tunnels, power cable and aerial transmission line monitoring and other industrial applications. More than 2500 systems have been installed in world-wide projects. Most of these applications are safety relevant and require high reliability and uptime of the sensor system.

The WELL.DONE DTS product series was carefully designed and thoroughly tested targeting reliable performance and smooth operation in industrial environments. Excellent Mean-time-between-failures (MTBF) of 28 years was reached based on the latest statistical field analysis of the DTS product.

lios-well_done-sensor-cable

The WELL.DONE system uses a fibre optic cable as the downhole sensor.

Various different cable designs and fibre types are available to use the WELL.DONE DTS in almost all kind of downhole applications including those with high hydrogen concentration and high temperatures up to 450 °C. LIOS Technology provides the appropriate multimode and singlemode cable. LIOS special single mode high temperature fibre has the advantage that it is unaffected by hydrogen usually causing the darkening of the fibre. The coatings of the optical fibre and the extrusion can be tailored to optimally suit the required resistance to temperature conditions and mechanical impacts.
