Filling level sensor
View Patent ↗The invention relates to a filling level sensor for a fuel tank 2, comprising a ceramic mounting plate 5 with a resistance network 6 arranged thereon and a contact structure 8 for the detection of an electrical filling level signal, and a cover 9 connected to the mounting plate 5, the cover 9 and the mounting plate 5 forming a housing 10. The cover 9 is strengthened in its edge area.
1. A filling level sensor for a fuel tank, comprising:
a ceramic mounting plate with a resistance network arranged thereon and a contact structure configured to detect an electrical filling level signal; and
a cover connected to the ceramic mounting plate, the cover and the ceramic mounting plate forming a housing which surrounds the resistance network;
wherein the cover is strengthened at its edge area.
2. The filling level sensor as claimed in claim 1 , wherein the edge has a greater wall thickness than other wall areas of the cover.
3. The filling level sensor as claimed in claim 2 , wherein the strengthened edge area has a wall thickness of 0.8 mm.
4. The filling level sensor as claimed in claim 1 , wherein the cover has a uniform wall thickness of at least 0.8 mm.
5. A filling level sensor for a fuel tank, comprising:
a ceramic mounting plate with a resistance network arranged thereon and a contact structure for the detection of an electrical filling level signal;
a cover connected to the ceramic mounting plate, the cover and the ceramic mounting plate forming a housing; and
a metal frame is fitted on a side of an edge of the cover remote from the ceramic mounting plate;
wherein the cover is strengthened at its edge area.
6. A filling level sensor for a fuel tank, comprising:
a ceramic mounting plate with a resistance network arranged thereon and a contact structure for the detection of an electrical filling level signal;
a cover connected to the ceramic mounting plate, the cover and the ceramic mounting plate forming a housing; and
metal strips arranged along lateral faces of the cover on a side of an edge remote from the ceramic mounting plate;
wherein the cover is strengthened at its edge area.
7. The filling level sensor as claimed in claim 6 , wherein the metal strips are arranged on the edge along two lateral faces.
8. The filling level sensor for a fuel tank, comprising:
a ceramic mounting plate with a resistance network arranged thereon and a contact structure for the detection of an electrical filling level signal;
a cover connected to the ceramic mounting plate, the cover and the ceramic mounting plate forming a housing; and
fillet joints applied in areas formed by a lateral face and an edge of the cover;
wherein the cover is strengthened at its edge area.
9. The filling level sensor as claimed in claim 8 , wherein the fillet joints are soldered into the areas formed by the lateral face and the edge.
10. The filling level sensor as claimed in claim 7 , wherein the metal strips are oriented longitudinally on the edge along the two lateral faces.
