Abstract: Disclosed is a level sensor (7) for a fuel tank (1), comprising a holding part (11) that can be mounted in different positions on a support (13). The support (13) is fastened to a swirl pot (4) while the holding part (11) bears a lever arm (8) that supports a float (9). The inventive level sensor (7) can be adjusted to different fuel tank dimensions by mounting said level sensor (7) differently on the support (13).

Abstract: The invention relates to a float (5) for a fill level sensor, comprised of a fuel-resistant plastic (7), an expanding means (8) and/or filler (9), whereby the expanding means consists of gas-filled plastic balls (11) that are provided in the form of microspheres (8), and the filler consists of micro-hollow balls (9). The microspheres (8) and the micro-hollow balls (9) are surrounded by fuel-resistant plastic (7).

Abstract: In the case of a filling level sensor (1) for detecting a fuel filling level in a fuel tank (2), a lever arm (7) which secures a float (6) has a guide part (14). The guide part (14) interacts with an installation opening (3) in the fuel tank (2) and deflects the lever arm (7) in a designated direction. This avoids the filling level sensor (1) being damaged during installation in the fuel tank (2).

Abstract: In a level sensor (2) for a fuel tank, one end of a lever wire (7) is located at a distance from a bearing (11) of a bracket (5). The bracket (5) has two limbs (12, 13) of which one holds the lever wire (7) and the other controls the signal transmitter (8). This enables the level sensor (1) to be calibrated in a particularly easy manner.

Abstract: Disclosed is a passive magnetic position sensor comprising contacting spring elements (5, 6) that can be moved against a resistance device (4) with the aid of a magnet (2) and are provided with two tongues (10,11) by means of which the contacting spring elements (5, 6) face a contact (7). The magnet (2) is able to press both tongues (10, 11) against the contact (7). If one of the tongues (10, 11) is prevented from being contacted as a result of the contact (7) being soiled (12),the other tongue (10, 11) is used for contacting, thus providing the position sensor with high redundancy.

The inventive level sensor (7) can be adjusted to different fuel tank dimensions by mounting said level sensor (7) differently on the support (13).

Abstract: The invention relates to a filling level sensor for a fuel tank with a float which is fastened to a lever arm and at least one contact which is arranged on the lever arm and is in connection with a slider track formed as a thick-film resistor. The thick-film resistor consists of at least two precious metals, one precious metal being silver and present in a smaller proportion than the other precious metal.

Abstract: The invention relates to a filling level sensor having a lever arm 8 which has a float at one end and is held at its other end by a clip 5, a carrier 1 composed of plastic, a bearing, arranged on the carrier 1, for the clip 5 and/or the lever arm 8, a filling level sensor 4 which is arranged on the carrier 1 and which is composed of a lid and a substrate 3, a resistance network which is arranged on this substrate 3 and to which a contact structure is assigned, the electrical connection of the contact structure to the resistance network producing an electrical signal for the filling level as a function of the pivoted position of a lever arm 8, and having at least one permanent magnet 12 which has the purpose of activating the contact structure.

Abstract: The invention relates to a level transmitter, having a lever arm which carries a float at one end and is received by a bracket at its other end, a support made of synthetic material, a bearing arranged on the support for the brackets and/or the lever arm, a level sensor arranged on the support and comprising a cover and a substrate, a resistor network arranged on this substrate and associated with a contact structure, with the electrical connection of the contact structure generating, with the resistor network and as a function of the pivotal position of a lever arm, an electrical signal indicating the level, and having at least one permanent magnet for actuating the contact structure. The bracket is made of an electrically conductive synthetic material and, at least in the region between the bearing and the cover, the support is made of an electrically conductive synthetic material.

Abstract: A filling level sensor (1) for a fuel container having a bracket (4) which can pivot by means of a carrier (5) has an opening (9) in the carrier (5). A measuring tip (13) can be lead through the opening (9) toward a component which is connected to contacts (10) of a potentiometer (7) and a lifting-off force of the contact (10) can be determined. The lifting-off force is thus measured in a low-friction fashion and near to the contacts (10).

Abstract: In a magnetically passive position sensor, a mechanical axis (11) and a magnetic axis (12) of a magnet (2) point toward the same contact spring element from two or more contact spring elements (5, 6). This results, in particular, in the end regions of the position sensor achieving a particularly high accuracy. The magnet (2) has a guide polygon (8) which is used to hold the magnet (2) in a holder (10) such that it cannot rotate.

Abstract: During the determination of a fill level of liquid in a container, a measuring chamber, in which there is initially the same fill level as in the container, is completely filled with liquid. The time required for completely filling the measuring chamber is measured and compared with previously determined values. The fill level in the container is then determined by comparison of the measured values with the known values.

Abstract: In a lever transmitter for a fuel tank, two spring tongues, each with a sliding contact, are arranged on a contact plate of a potentiometer. The contact plate is prestressed against sliding tracks of the potentiometer by a spring element fastened to the carrier and having the sliding contacts due to vibrations are thereby reliably avoided.
