Abstract

A sensor arrangement for installation in a carriageway includes a piezoelectric measuring arrangement disposed in a cavity of a hollow profile and in mechanical contact with the hollow profile. The hollow profile includes an external force introduction surface, which is configured to transmit a weight force onto the piezoelectric measuring arrangement, which outputs electrical signals proportional to a magnitude of the weight force. The sensor arrangement includes a separating element, which is configured to prevent a rolling force acting on the separating element from being transmitted into the hollow profile. The separating element includes at least one distribution opening configured to permit grout to flow through the distribution opening.
