With the Luna EN.SURE cable strain measurement system it is possible to measure the strain put on your power cable when unforeseen events happen and take the appropriate action - saving time and money on downtime and making sure your cables are always ready to run at maximum capacity and preventing large-scale cable faults. Let LIOS EN.SURE ensure a reliable supply of electrical power for today’s world.
Long power cables and other similar structures are susceptible to forces from many unforeseen influences – excavators digging a new road, an anchor being pulled behind a boat, earthquakes, etc. By integrating a Luna EN.SURE next to your cables you now have the possibility to monitor your cables and assess damages that may be forced upon them.
The EN.SURE is a series of controllers for distributed structure monitoring (DSM) that is based on proprietary Brillouin measurement technology. Its major advantages are the excellent distance range and measurement performance in combination with the passively cooled and maintenance-free industrial design. It exhibits a superior strain and temperature resolution and accuracy in comparison to other technologies. The excellent performance is achieved in both, single- and double-ended fiber configurations.
Features
- Highly reliable industrial design
- Signal processing based on patented Raman OFDR Technology
- Superior hotspot detection along the whole sensor cable length
