Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
120 words
Control sensor for a construction machine for generating height control signals by detecting the relative position of the sensor to a guide cable, wherein: the control sensor comprises at least two supersonic sensors, at least one of which serves as a transmitter/receiver element; the supersonic sensors are connected to an evaluation means which serves to generate the height control signals and a signal of direction which indicates the exceeding of a certain range of width; and the supersonic sensors are positioned at a right angle to the direction of movement of the construction machine, and are arranged at a distance from the guide cable that detection angles of supersonic sensor cones generated by said supersonic sensors overlap at said distance.
Claim 2
Dependent Claim
120 words
Control sensor for a construction machine for generating height control signals by detecting the relative position of the sensor to a guide cable, wherein: the control sensor comprises at least two supersonic sensors, at least one of which serves as a transmitter/receiver element; the supersonic sensors are connected to an evaluation means which serves to generate the height control signals and a signal of direction which indicates the exceeding of a certain range of width; and the supersonic sensors are positioned at a right angle to the direction of movement of the construction machine, and are arranged at a distance from the guide cable that detection angles of supersonic sensor cones generated by said supersonic sensors overlap at said distance.
Claim 3
Dependent Claim
21 words
Control sensor according to claim 1, wherein the supersonic sensors are cast in a block of plastic in equidistant spaced-apart relation.
Claim 4
Dependent Claim
26 words
Control sensor according to claim 2, wherein the supersonic sensor cones overlap at a distance of 40 cm from said supersonic sensors to said guide cable.
Claim 5
Dependent Claim
