The DiTemp® Self Heating Temperature Sensing cable is a unique sensor for the evaluation of distributed temperature over distances up to 1.5 km. The  DiTemp® Self Heating Temperature Sensing cable is used in a range of hydro & geo-technical applications that require distributed temperature sensing, where the temperature contrast between the ground and the fluid to be monitored is not sufficient to provide a reliable detection. The  DiTemp® Self Heating Temperature Sensing cable is particularly used in the monitoring of dams, dikes, embankments and levees just to name a few. The DiTemp® Self Heating Temperature Sensing cable is a fiber optic cable, with a central construction around a FRP strength member. Different plastic loose tubes are allocated both for dual layer acrylate coating for increased micro bending performance and isolated copper wires. The isolated copper wires permit to heat the cable up to relative short distance thanks to the low resistivity. The outer HDPE sheath ensures the cable to be watertight.
This sensor is particularly suitable for outdoors and harsh environment applications with different methodology of installation: direct burial in the ground or concrete or anchored to an already existing structure. Thanks to the special package design the DiTemp® Self Heating Temperature Sensing cable offers high tensile strength, crush resistance, lateral water tightness, chemical and abrasion resistance and standard rodent protection. The DiTemp® Self Heating Temperature Sensing cable is fully compatible with the DiTemp® system and all its accessories.
