  • Publication number: 20240192070
    Abstract: A flow-through pressure transducer comprising a cylindrical diaphragm positionable to allow fluid to flow therethrough which responds to variations in fluid pressure to generate an electrical signal proportional to such variations and which is incorporated in a housing for interconnecting with fluid delivery tubing. The diaphragm is made of relatively thin resilient metal, shaped to be a tube, elliptical in cross-section, with transducers, located on the elliptical major and minor axes which change their electrical state in response to movement of the diaphragm walls, and which are coupled in a bridge circuit for signal measurement. The housing is constructed for either gage or absolute fluid pressure measurements.

  • Patent number: 11913850
    Abstract: A measuring system for a physical variable, the measuring system having a housing, a measuring tube having at least one tubular deformation body having a cross-section which is deformed at least partially and which is configured to expand elastically under pressure, two feed sections attached to end sections of the deformation body, two sealing sections for sealingly coupling the measuring system to a process, and two molded support sections to carry the housing. A measuring sensor system measures values of at least one of a stretching or a widening at at least two points on a section of the deformation body. An evaluation unit evaluates measured values of the stretching and widening and outputs them as a measurement signal. The housing at least partially surrounds and stabilizes the measuring tube on an outside and is provided with a vacuum and/or a negative pressure compared to the outside atmosphere.
