  • Patent number: 6718828
    Abstract: Described is a sensing device, which is suspended in a filling material, particularly a liquid, by means of a cable 30. The cable 30 consists of a cable jacket of insulating material, a shielding jacket 32 of metal mesh beneath the cable jacket 31, and the electrical conductors connected to the sensor proper 11. In accordance with the invention, the shielding jacket 32 also serves to relieve pull. To this end, the end 33 that projects into the sensor housing 10 is exposed, i.e., is free of the insulating jacket material, and has a solid mechanical connection to the adapting piece 21 of a cable seat 20 inserted into the housing 10, and the connection is electrically conductive.

  • Patent number: 6561037
    Abstract: The invention pertains to a pressure sensor for a pressure measuring transducer which contains a base body (3), and a pressure-sensitive measuring membrane (7). The membrane is located on the base body (3) and can be subjected to a measurable pressure. The first chamber (10) is arranged between the base body (3) and the measuring membrane (7) in order to protect the measuring membrane (7) if the pressure to be measured exceeds an upper pressure limit. A second chamber (11) is provided to protect the measuring membrane (7) if the pressure to be measured falls short of a lower pressure limit. The second chamber (11) is arranged between the measuring membrane (7) and a contact plate (5) The contact plate is situated on the side of the measuring membrane (7) opposite the base body (3). A bore (6) is provided for subjecting the measuring membrane (7) to pressure.
