Trisens® Cable

Trisens® is our ultra-thin signature optical sensorWith an outer diameter of just 3 mm, Trisens® is optimized for acousticstrain, and temperature monitoring. It also performs tremendously when faced with other sensing applications and data transmission. The outer plastic sheath and high-grade steel tube give the cable enhanced flexibility and high resistance to mechanical stress. 

Trisens® weighs only 11 kg/km, incredibly light for a high-performing optical sensor cable. It’s an excellent sensing solution for direct installation and comes ready for deployment. Its uniquely thin diameter and low weight also make it a preferred option for integration in larger optical fiber configurations.
