Abstract:
    The invention relates to a linear heat detector based on thermocouple principle. It includes detecting cable and voltage signal measuring device. The detecting cable at least includes two detecting conductors and semiconductor layer, fusible insulated layer and conductive layer. The linear sensor would cause dissolution to the fusible insulated layer and generate thermocouple effect to output fire alarming signal. The voltage of voltage signal measuring device is corresponding to the temperature of highest section of the detecting cable and it has high reliability. The invention adopts passive detecting method and is very safety.
