Thermocouple type distributed sensor and disaster prevention system

摘要

PROBLEM TO BE SOLVED: To provide: a thermocouple type distribution sensor in which, a thermocouple part is connected to connection wire to form thermal sensing wire assembled with return wire in parallel with thermocouple wire to enable roll winding, thereby enabling assembly of the thermocouple wire at a factory; high quality management and stability of the thermocouple wire are achieved, and loads of work at a construction site is reduced and assembling mistake can be eliminated; and a disaster prevention system with the thermocouple type distribution sensor.SOLUTION: A thermocouple type distribution sensor includes: both sides of at least a pair of thermocouples in which two kinds of metal "a" and metal "b" are mutually conjugated are made of the metal "b"; and a thermocouple part 5 in which at least the pair of thermocouples is connected to conductor wire 9 having length equal to a thermocouple unit or less and having flexibility. The thermocouple part 5 can be bent at a portion of the conductor wire 9.SELECTED DRAWING: Figure 1
