Abstract
A filling level sensing device for a liquid reservoir, in particular for a compensation tank of a vehicle brake system, includes at least one float, at least one sensor element connected to the at least one float, and at least two sensors for detecting the position of the at least one sensor element. The float may be designed to come into contact with the liquid in the liquid reservoir. At least one of the two sensors may sense a change in the filling level of the liquid reservoir depending on the position of the at least one sensor element relative to the at least two sensors.

A filling level sensing device for a liquid reservoir, in particular for a compensation tank of a vehicle brake system, comprising:
- at least one float which is designed to come into contact with the liquid in the liquid reservoir,
- at least one sensor element which is connected to the at least one float, the at least one sensor element producing a magnetic field, and
- at least two sensors for detecting the position of the at least one sensor element, the at least two sensors reacting to the magnetic field which is produced by the at least one sensor element, one sensor of the at least two sensors having a higher magnetic sensitivity than the respectively other sensor, wherein at least one of the sensors senses a change in the filling level of the liquid reservoir depending on the position of the at least one sensor element relative to the at least two sensors.
