Abstract: A mounting device for mounting non-contacting distance sensors to a variable-height implement of a paver or other construction vehicle is disclosed. The mounting device includes two extension arm assemblies, each extension arm assembly having an inner section and an outer section that are movable relative to each other, with the inner section being mounted to the variable-height implement. The mounting device further includes a beam assembly attached to the outer sections of the extension arm assemblies. The beam assembly includes a beam and mounting brackets for attaching a plurality of non-contacting distance sensors to the beam.
