Abstract
A high-pressure sensor includes a deformation member and connection piece that is joined to the deformation member by a welded seal. The deformation member has a truncated-cone-shaped circumferential segment, via which a welding current can be supplied, in order to weld the two pieces to each other in response to a simultaneous pressing together of deformation member and pressure connection piece. A welding electrode that is configured in a cup shape having a spring-loaded nonconductive insert that can be axially displaced in the interior of the cup.
Claims9
A high-pressure sensor comprising:
- a deformation member including a truncated-cone-shaped circumferential segment;
- and a pressure connection piece joined to the deformation member by a welded seal;
- wherein the truncated-cone-shaped circumferential segment converges towards the pressure connection piece;
- and
- an electrically conductive contact ring that is mounted on the truncated-cone-shaped circumferential segment without a direct conductive connection to the pressure connection piece.
