  • Differential pressure transmitter with simplified structure and reduced edge effects
    Patent number: 6772641
    Abstract: A differential pressure transmitter for sensing a physical variable related to a process fluid of an industrial system having a main body and a secondary body. The main body comprises a containment enclosure and a base that is associated with the containment enclosure. The secondary body comprises a first connection element that comprises a first coupling surface at which the secondary body is associated with the base of the main body. The secondary body comprises at least one second connection element that comprises a second coupling surface at which the second connection element is associated with the first connection element. The second connection element is rigidly connected to the first connection element to reduce edge effects on a separation membrane and to constitute a single mechanical structure together with said first connection element that is not separable into constituent parts of the first connection element and the second connection element.
