Abstract
An inclination sensor, in particular for measuring an inclination of service lines and/or ram boring machines, comprising a pendulum arranged in a measuring cell and at least one displacement sensor measuring the deflection of the pendulum. The pendulum comprises a body moving on a circular arcuate path in the measuring cell, the length of the pendulum being the same as the radius of the path. In this way a pendulum length can be obtained that is larger than the diameter of the measuring cell so as to obtain a large deflection of the body for a given angle and thereby achieve high sensitivity and accuracy of measurement.
