Abstract
PURPOSE:To manufacture a titled temperature sensor to be used for detecting the location of abnormal temperature which stably functions for a long period with a simple structure, by connecting in series plural temperature sensitive switches which make off-operations at temperatures which are higher or lower than a prescribed temperature and by combining said switches with a device which transmits and receives pulses. CONSTITUTION:This device is so arranged that pulse signals are impressd from one end of a temperature sensor made by connecting in series plural temperature sensitive switches which make off-operations at temperatures which are higher or lower than a prescribed temperature, and reflected pulse signals fom the locations of the above-mentioned temperature sensitive switches which make off-operations are received, and then, the locations are calculated from the time difference. For example, numerous temperature sensitive switches 14 which make off-operations at temperatures at temperatures higher or lower than a prescribed temperature and which are connected in series through a conductor 13a, are installed together with another conductor 13b along a pipe 11. When poulse signals are impressed on them from a pulse generator 31, and the returning time of reflected pulses is detected by a time difference detector 32, and then, the distance is calculated by a location orientator 33, the distance to a temperature sensitive switch which is under off-conduction due to an abnormal temperature is obtained.
