Face is all surrounded by one layer of temperature-sensitive and the material of insulation, and under normal monitoring state, two steel wires, all in state of insulation, work as surrounding enviroment
The when that temperature rising to predetermined action temperature, temperature-sensitive material will rupture, and two steel wires can produce short circuit, and input module is examined
Produce warning after finding short-circuit signal immediately, belong to " switching value " temperature sensing cable.But, along with the expansion of temperature sensing cable application
Exhibition, in industry, the technology to temperature sensing cable requires the most constantly to deepen, and " analog quantity temp.-determined type " occurs the most again and " analog quantity difference is fixed
" temperature sensing cable, its core number is also become four cores from two traditional cores to temperature formula.Four core analog quantity temp.-determined type temperature sensing cables, by four
Core forms, and during variations in temperature, between quad, resistance changes, and when resistance variations reaches the alarming threshold value set, visits
Survey device and send fire alarm signal.Four core analog quantity different constant temperature formula temperature sensing cables, are made up of four cores, during variations in temperature, and four
Core is led line resistance and is changed, and when resistance variations speed or variable quantity reach the alarming threshold value set, detector sends difference
Warm fire calamity or constant temperature fire alarm signal.Then, existing temperature sensing cable has operating temperature and the temperature difference between temperature of being failure to actuate
Greatly, trigger the shortcomings such as warning sensitivity is lower, use demand can't be fully met.
Summary of the invention
