Abstract
A method of magnetic sensing uses at least two magnetic sensing elements including a first and a second magnetic sensor element. The method includes: a) measuring in a first configuration a combination of the first and second signal obtained from both sensors; b) measuring in a second configuration an individual signal obtained from the first sensor only; c) testing a consistency of the combined signal and the individual signal, or testing a consistency of signals derived therefrom, in order to detect an error. A sensor device is configured for performing this method. A sensor system includes the sensor device and optionally a second processor connected thereto.
