Abstract
The present invention relates to a sensor device comprising four or more sensor elements. A controller comprising a control circuit controls the sensor elements to measure an environment attribute, produces more than two values corresponding to the measurement and compares the values to determine a fault. The more than two values are obtained by different combinations of sensor elements that have at least one sensor element in common and one sensor element that is not in common. The values can be measured in different coordinate systems and the control circuit can convert the field vectors into a common coordinate system.
