  • Sensor device with self-test capability
    Patent number: 8938364
    Abstract: A sensor device includes: a sensor module mounted on a conductor board; a sensitive element which is sensitive to a variable; a self-test control unit implementing a self-test program, the self-test control unit applying a self-test variable to the sensitive element, taking the self-test program into account; a detection unit detecting a characteristic of the sensitive element which is altered as a result of the applied self-test variable and providing an actual self-test response, taking the altered characteristic into account; and a comparator unit provided on or in the sensor module, the comparator unit comparing the actual self-test response to at least one specified setpoint self-test response and providing comparative information.
