LDN Series

Harsh area linear heat detection cable

System Sensor's linear heat detection system is a fixed temperature device consisting of the conductor cable and
an EOL box. When heated to the rated temperature, the heat sensitive polymer insulation melts allowing the inner conductors to
contact each other initiating an alarm state. This type of detection is widely used in industrial,
petrochemical, refinery and power generation plants.



    • Continuous sensitivity along the length of cable
    • Easy to install, test and splice
    • Chemical resistant
    • UV resistant
    • available in 68,78, 88 and 105 degree celsius
