| description | A sensor for measuring deformation of an underground pipe line is provided to maximumly shorten the repair time of the underground pipe line by precisely analyzing the deformation and leakage of the underground pipe line for sections. A measurement sensor(1) is installed at a lower portion of an underground pipe line and measures deformation of the underground pipe line through a measurement unit(2). The measurement sensor includes a case band(13). A plurality of insertion holes(131) are provided in the case band. At least one displacement measurement optical fiber(11) and at least one temperature measurement optical fiber(12) are inserted into the insertion hole. The displacement measurement optical fiber and the temperature measurement optical fiber are communication optical fibers. If light is illuminated through one end of the communication optical fiber, the wave of the light is reflected by the other end thereof. |
