Temperature sensor equipped with abnormal temperature detection function
专利汇可以提供Temperature sensor equipped with abnormal temperature detection function专利检索，专利查询，专利分析的服务。并且PURPOSE: To detect accurately a bursting (abnormal) position by providing pressure detectors in both sides of a detection element, which consists of a long thermo- plastic resin tube where an internal pressure is given, and detecting the pressure drop in the tube which is generated by a local thermal bursting of the element.
CONSTITUTION: Pressure detectors 2 and 3 and timers 4 and 5 are provided at both ends of detection element 1 where plural thin pipes consisting of thermo-plastic resin are connected by connectors 6 and inactive gas is pressured and enclosed internally; and when the pressure in element 1 drops due to the local thermal bursting of pipes, signals are sent from pressure detector 2 (3) to timer 4 (5) at set pressures P
1 and P
2 , and time T
1 (T
2 ) from P
1 to P
2 is measured. Next, the value of k is obtained from the measured times T
1 and T
2 above and the expression (R
j A and R
j B are fluid resistances in the connector part in the A side and the B side; L is the half length of element 1; Rl is a resistance; α is a constant), and next, distance l to the bursting position (× mark) is calculated from expression l=kL.
