Abstract
A signal transmitter for a fill level sensor, a conductor path arrangement is printed on a resistor arrangement. The resistor arrangement is located below a slideway and is accessible between conductor path sections for trimming of the resistor. The signal transmitter is of particularly compact configuration and can be produced at low cost.
Claims12
A signal transmitter for a fill level sensor of a container of a motor vehicle configured to produce electric signals as a function of a fill level, comprising:
- a resistor arrangement,
- a conductor path arrangement having a slideway and arranged on the resistor arrangement and connected to the resistor arrangement, and
- a sliding contact configured to move in accordance with the fill level and slides across the slideway of the conductor path arrangement,
- wherein the resistor arrangement and the conductor path arrangement at least partially overlap,
- wherein the resistor arrangement defines at least one material recess arranged between two sections of the resistor arrangement that are covered by two mutually adjacent conductor path sections.

A method for producing a signal transmitter for a fill level sensor of a container, comprising:
- applying a conductor path arrangement to a resistor arrangement;
- wherein the conductor path arrangement is connected to the resistor arrangement, and
- wherein the resistor arrangement and the conductor path arrangement at least partially overlap;
- and
- trimming the resistor arrangement to specified resistance values with a laser beam by removal of material after the application of the conductor path arrangement,
- wherein the resistor arrangement is trimmed to the specified resistance values by directing the laser beam at the resistor arrangement while moving it between two adjacent conductor path sections to perform the removal of material.
