  • Patent number: 10473544
    Abstract: A device for measuring a fluid pressure and for verifying the fluid pressure that has been measured comprises a sensor element having a fluid chamber and an element that adjoins said fluid chamber and can be deformed under fluid pressure, a resistance bridge being arranged on the deformable element side that faces away from said fluid chamber, for the purpose of generating a transverse bridge voltage dependent on said fluid pressure. The device also comprises a voltage divider which is connected in parallel to said resistance bridge for generating a differential voltage.

  • Patent number: 9266517
    Abstract: A sensor assembly for use with a master cylinder is described. The master cylinder comprises an input-side activation element to which a signal transmitter element is coupled. The sensor module comprises a travel sensor for sensing travel carried out by the activation element, and a position sensor for sensing when a predefined position of the activation element is reached.

  • Patent number: 8978457
    Abstract: A sensor module for use with a master cylinder of a brake system is described, wherein the master cylinder has an input-side activation element and an underpressure region for communicating with an underpressure brake booster. The sensor module comprises an underpressure sensor for detecting an underpressure in the underpressure region of the master cylinder as well as at least one further sensor for detecting a signal transmitter which is rigidly coupled to the activation element. The underpressure sensor and the at least one further sensor are accommodated in a housing of the sensor module. An opening in the housing permits communication between the underpressure sensor and the underpressure region of the master cylinder.
