A position signal generator for an electronic position measuring device is disclosed. In an embodiment, the position signal generator includes a signal generation device for generating a periodic magnetic signal, and an electric power supply device for supplying the signal generation device with electric energy. The position of the position signal generator is determined via the position measuring device.

Position sensor, position measuring device and method for the operation thereof

A motion sensor which has a coil that surrounds a ferromagnetic core and at least one magnet that is longitudinally movable along the coil. The magnet causes a magnetic saturation of the ferromagnetic core in an associated zone that covers a portion of the length of the coil. An evaluation unit generates a position signal in dependence on the position of the movable magnet along the longitudinal extent of the coil. The coil has at least two superimposed winding layers that surround the ferromagnetic core and are wound in opposite directions. The windings of adjacent segments generally have about the same width over which the winding density remains constant. Thus, the winding density of the segments of one of the winding layers increases linearly over the length of the sensor while the winding density of the segments in the other winding layer linearly decreases over the sensor length.

Method for determining the viscosity of an operating liquid of an internal combustion engine

A method of determining the viscosity of an operating liquid, such as engine oil, in an internal combustion engine uses a sensor having a measuring chamber for determining the liquid level and its variation. The measuring chamber is connected via a damping device to a reservoir of the operating liquid. On starting the internal combustion engine, the variation in the liquid level is measured in the measuring chamber of the sensor and the variation of the level over time is used as a measure for determining the viscosity.
