  • 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).
    Type: Grant

  • Transfer fluid for pressure measurement technology and its application
    Patent number: 6845674
    Abstract: Transfer fluid, in particular for electrical pressure transducers and pressure transmitters, that transfers deflections of a separating element between a substance to be measured and the transfer fluid to a pressure measurement arrangement, the transfer fluid comprising a polyalphaolefin (PAO 6).
