FIELD: physics.
SUBSTANCE: sensor for searching for defects in underground utility lines has a cowling in whose bottom part there is a membrane with a piezoelectric element pressed to the said membrane, and a cover joined to the cowling. A holder is built into the cover in form of a pipe on whose ends of which there are electromagnetic antennae spaced apart by a basic distance and leads from the electromagnetic antennae and piezoelectric elements are connected to a computer.
EFFECT: easier search for underground utility lines and easier search for defects on said lines.
