SET-UP FOR MEASURING A ROTATIONAL SPEED, IN PARTICULAR, OF A TURBOCHARGER OF A MOTOR VEHICLE

摘要

For a set-up for measuring a rotational speed of a turbocharger of a motor vehicle, including at least one antenna for generating and/or receiving electromagnetic radiation and an electronic module having at least one electric and/or electronic component and being electrically connected to the antenna. The set-up further includes a housing shell made at least partially of laser-absorbing material and having an inner chamber, and a housing cover, which rests on at least one laser-absorbing contact surface of the housing shell and covers the inner chamber of the housing shell at least partially, and at least sections of which are made of material transparent to laser radiation; the antenna and the electronic module being situated in the inner chamber of the housing shell, and at least sections of the housing cover being welded to the housing shell at the at least one contact surface using a laser-welded seam.

1. A set-up for measuring a rotational speed of a turbocharger of a motor vehicle, comprising:
at least one antenna for at least one of generating and receiving electromagnetic radiation; an electronic module, which includes at least one of an electric and electronic component, the electronic module being electrically connected to the antenna; a housing shell which is made at least partially of laser-absorbing material and includes an inner chamber; and a housing cover having a first side which abuts against at least one laser-absorbing contact surface of the housing shell and at least partially covers the inner chamber of the housing shell, and at least sections of the housing cover are made of material transparent to laser radiation, the antenna and the electronic module being situated in the inner chamber of the housing shell, and at least sections of the housing cover being welded to the housing shell at the at least one contact surface, using a laser-welded seam.
