A printed circuit board having conductor tracks formed on one side of a substrate. The substrate is able to be cohesively bonded at a contact face to a cover for protecting the conductor tracks. In this case, the substrate includes a step, which forms a barrier with respect to an auxiliary material for promoting the cohesive bond, in order to prevent any wetting of the conductor tracks with the auxiliary material. A sensor having a printed circuit board for use in a fuel filling level measurement system of a vehicle.

Printed circuit board and sensor

A ceramic card having a thick film network, with conductive vias formed as part of the card. Each of the vias is in electrical communication with both sides of the thick film network, allowing the pads and the pad senders to be formed on both sides of the card. This configuration maintains the contact when one of the connectors is subjected to bending force or is otherwise displaced, maintaining contact with at least one of the pads, and allowing the system to still function. The double sided thick film network allows for each connector to touch both sides of one of the pads, and still maintain electrical communication with the level sender, thus eliminating the failure mode of intermittent contact with the thick film network resulting from movement of the connector.

A device for contacting at least one conducting track has a contact spring that is connected to a pivotable bow by a pivot bearing. The contact spring also has spring elements connected in series for preloading contacts against the conducting track. An axis of the pivot bearing is arranged parallel to the direction of motion of the contacts over the conducting tracks.

Disclosed is a level sensor () for a fuel tank (), comprising a holding part () that can be mounted in different positions on a support (). The support () is fastened to a swirl pot () while the holding part () bears a lever arm () that supports a float (). The inventive level sensor () can be adjusted to different fuel tank dimensions by mounting said level sensor () differently on the support ().

In a level sensor () for a fuel tank, one end of a lever wire () is located at a distance from a bearing () of a bracket (). The bracket () has two limbs () of which one holds the lever wire () and the other controls the signal transmitter (). This enables the level sensor () to be calibrated in a particularly easy manner.
