Sensor device with a sensor element for mechanical stresses

摘要

The invention relates to a sensor device with a sensor element (16), with the mechanical stresses can be measured. According to the invention, provision is made, for measuring the voltages force transducer (11) with a weakened region (15) are used for. The weakened regions (15) form, together with a core (17) a magnetic circuit (22), so that stress conditions, which is in the weakened area (15), the impression of a force, for example, on an external structure (13), vary, with the aid of the magnetoelastic effect by means of a control device (23) can be detected. The mechanically weakened region (15) is increased, therefore, the sensor sensitivity, wherein the force transducer (11), taking into account the mechanical application can be designed. This way, it can be advantageously a sensitive sensor device with flexible applications provide.
