  • Patent number: 7451779
    Abstract: A universal mounting bracket is provided for coplanar and bi-planar differential pressure (DP) transmitters, and gauge pressure transmitters. The bracket includes a support defining a plurality of planes, with at least two sets of bracket mounts disposed on mutually orthogonal planes. At least two sets of coplanar DP transmitter mounts are also disposed on mutually orthogonal planes, and at least one set of bi-planar DP transmitter mounts is configured for mounting the bi-planar DP transmitter in any one of a plurality of mutually orthogonal orientations. The bracket also includes at least two sets of gauge pressure transmitter mounts on mutually orthogonal planes.

  • Patent number: 6918303
    Abstract: A pressure transmitter apparatus includes a unitary body with two, normally vertical pressure passageways communicating respectively between opposed pressure openings extending normally horizontally through the body portion. A transducer for generating a differential pressure signal mounts on a transducer mounting element, coupled to the body portion and located above the pressure passageways. A pair of diaphragm elements can form first and second process diaphragms, closing first and second pressure openings. Flange elements overlie the diaphragm elements and are removably and replaceably secured to the body portion, having liquid drainage and gas purging passageways. A flame retardation element can be disposed within at least one of the pressure passageways. An overrange protection element can be integrally arranged with the unitary body portion to protect the transducer from overrange pressure fluctuations.
