  • Rotation angle sensor for a stator
    Patent number: 10955262
    Abstract: A rotary sensor includes a stator element and a rotor element that is rotatably mounted in respect of the stator element about an axis of rotation. A rotary angle can be captured by inductive coupling between the rotor element and the stator element. The rotary sensor further includes a measuring device configured to capture the rotary angle depending on the inductive coupling between the rotor element and the stator element. The stator element has at least one transmission coil for emitting alternating electromagnetic fields and at least two reception coils for capturing alternating electromagnetic fields, when the measuring device is configured to excite the at least one transmission coil with at least two mutually different frequencies for emitting at least two alternating electromagnetic fields.

  • TRANSIT TIME CORRECTION IN A FLOW SENSOR
    Publication number: 20100288055
    Abstract: A sensor measures a flow quantity of a medium using a first wave converter and a second wave converter which faces the first wave converter, each of which emits and receives sound waves, and a device calculates the flow quantity on the basis of a first wave transit time from the first wave converter to the second wave converter, and on the basis of a second wave transit time from the second wave converter to the first wave converter. The device includes a unit for limiting the change to the flow quantity. In this manner, and the measurement may be carried out more accurately.
