Abstract
A device for detecting the movement of a movable component in that the position signals furnished by two position sensors are added to form a signal that is conducted through a line to an evaluation arrangement. The position ranges associated with the position sensors have an overlap region. Different discrete values are assigned to the position signals and can be evaluated easily in the evaluation arrangement.
Claims14
A device for detecting movement of a movable component, said device comprising:
- a first position sensor for outputting a first signal corresponding to at least a first position range of the movable component when the first position sensor senses the movable component within the first position range, the first signal having a single first discrete value;
- a second position sensor for outputting a second signal corresponding to at least a second position range of the movable component when the second position sensor senses the movable component within the second position range, the second position range having an overlap region with said first position range, said second signal having a single second discrete value which is different from said first discrete value;
- means for adding the respective discrete values of said first and second signals to produce a discrete sum signal, and for feeding the discrete sum signal to a single signal line;
- and
- an evaluation arrangement connected to said single signal line for receiving and evaluating the sum signal on said single signal line and determining movement of the movable component based on the sum signal.
