ABSTRACT:
A control sensor for a construction machine serves for generating height control signals for the height control of a tool of the construction machine along a guide cable and contains at least two supersonic sensors, one of which at least serves as a transmitter/receiver element, whereby the supersonic sensors are connected to an evaluation means and arranged in a right angle to the construction machine's direction of movement and in such a distance to the guide cable that the detection angle of the supersonic cones will lead, at this distance, to their overlapping.
