  • SENSOR FOR DETECTING PRESSURE AND/OR FILLING LEVEL AND/OR FLOW RATE AND/OR DENSITY AND/OR MASS AND/OR TEMPERATURE
    Publication number: 20220034732
    Abstract: A sensor for detecting pressure and/or filling level and/or flow rate and/or density and/or mass and/or temperature, wherein a sensor component is coupled to a further sensor component by nanowires, and wherein the sensor components are fixed, sealed or electrically contacted to one another. For example, a sensor component is connected directly to a printed circuit board through nanowires.

  • Pressure sensor
    Patent number: 6978678
    Abstract: The invention relates to a pressure sensor comprising a sensor element (2) having a flat membrane (4) which is transformed at its edge into a hollow-cylindrical ring (6) so that a central recess (20) is provided at the lower side (10) of the membrane (4). On the upper side (8) of the membrane (4) a resistance arrangement consisting of electric resistors is disposed. A sleeve (54) projects into the recess (20) and supports a first elastomeric sealing ring (66) which is tightly arranged at the circumferential area of the recess (20). Furthermore the sleeve (54) supports a second elastomeric sealing ring (68) which serves for sealing at a feeding tube for pressure fluid formed in a component part to which the pressure sensor is mountable. The sleeve (54) is rigidly connected to a disk (56) which is attached with its outer edge (58) to a casing (26) enclosing the sensor element (2).
