Abstract

The present invention relates to an clinometric optical fiber sensor of the clinometric tube type and dedicated to the measurement of displacement of sloped soils, the sensor comprises a tube (3) made of plastic material and at least three optical fibers (53), said three optical fibers (53) being arranged along the longitudinal axis of the tube (3) in an equidistant arrangement with respect to the other, and it is characterized in that a fourth optical fiber (53) it is inserted into the wall of the tube (3) but it is installed so as not to transmit deformations and being responsible for the measurement of the temperature profile; and within the tube there is a series of biaxial digital slant (slope) sensors (30), said slant sensors being arranged at equidistant intervals on from the other, and said slant sensors being provided with an electronic compass. It is also the object of the present invention to provide a process for the making of the present clinometric sensor.
