Linear Heat Detection Systems
|
The Zeta Heat tracer system consists of a control module, and a special 4 core heat tracer cable. The cable has 4 cores, 2 are covered with negative temperature co-efficient (NTC) material, the other 2 have normal PVC insulation. The cores are twisted together and protected by an outer sheath of high temperature flame retardent PVC insulation. The Primary mechanism of heat (fire) detection is that the dielectric between the 2 NTC cores is monitored for any change, and compared to the 2 PVC cores. Linear Heat Detection Systems Product Range
