Abstract: In a sensor assembly, a deformation body has two oppositely lying surfaces, an outer edge segment and a sensor blade extending from a surface outward. A protective apparatus protects the deformation body from pressure surges or abrupt changes of temperature on its surface. The protective apparatus includes at least one plate, extending radially inwardly so that a cavity is formed, which accommodates a region of the sensor blade adjoining the deformation body and remote from the distal end of the sensor blade, forming a gap between the plate and sensor blade. A sensor formed by the sensor assembly and a transducer element coupled therewith can be used for registering pressure fluctuations in a flowing fluid, such as steam having a temperature of 400 C and/or, a pressure of greater than 140 bar in order to measure flow parameters of the fluid.

Abstract: The sensor assembly comprises: a bowl shaped, namely at least sectionally dished, membrane, with a curved surface and an oppositely lying surface; and a sensor blade extending from curved surface of the membrane. The membrane is so formed that at least one region of the curved surface adjoining the sensor blade is convex. A sensor formed by means of such a sensor assembly and by means of a transducer element coupled therewith and serving for generating a sensor signal representing movements of the sensor blade changing as a function of time and/or deformations of the membrane changing as a function of time, or a measuring system formed by means of the sensor and a measuring electronics connected thereto, can be used for registering pressure fluctuations in a flowing fluid, such as, for instance, a 400 C hot steam, for instance, in order to measure a flow parameter of the fluid.

Abstract: A sensor assembly has a deformation body having two oppositely lying surfaces and an outer edge segment as well as a sensor blade extending from the surface to a distal end and having a left side, first lateral surface and a right side, second lateral surface. An overload protection apparatus protects the deformation body against plastic deformation and has a support stirrup led with lateral separation around the sensor blade and a first stop and a second stop located on opposite sides of the sensor blade. The stops are so arranged that an intermediate space formed therebetween receives only a portion of the sensor blade. The deformation body and the sensor blade are excitable to oscillate about a shared static resting position and to be moved in such a manner that the sensor blade executes pendulum-like movements elastically deforming the deformation body.

Furthermore, the sensor assembly comprises a protective apparatus for protection of the deformation body from pressure surges exerted against its surface and/or for protection of the deformation body from abrupt changes of temperature on its surface, The protective apparatus includes, adjoining the edge segment of the deformation body, at least one plate, which extends radially inwardly in the direction of the sensor blade in such a manner that, between plate and deformation body, a cavity is formed, formed, which accommodates a region of the sensor blade adjoining the surface of the deformation body and remote from the distal end of the sensor blade, and that a gap is formed between the plate and sensor blade.

Abstract: A vortex flow transducer for measuring the flow velocity of a fluid flowing in a measuring tube as well as to a vortex flow sensor for the vortex flow transducer. In such case, the vortex flow sensor includes a housing having a central axis and a connecting section, on which a shoulder is embodied, which has a bearing area. In a plane of the shoulder a membrane is arranged, whose edge is positioned over the bearing area and is axially spaced therefrom. The vortex flow sensor includes, furthermore, a flange shaped support system having a radial edge section and a cylindrical axial section, wherein the radial edge section lies with its surface against the shoulder of the platform and the cylindrical axial section extends parallel to the central axis, so that the membrane is supported against the support system upon application of a predetermined pressure on the membrane.

Abstract: A sensor module serves for registering a flow velocity and/or a volume flow rate, of a fluid flowing in a pipeline. The sensor module comprises a platform (PS) having, extending therein from an inlet opening to a drain opening remote therefrom and communicating with the lumen of the pipeline, a flow path for guiding a fluid volume portion branched from the fluid flowing in the pipeline and a transducer element for producing at least one sensor signal influenced by the fluid guided in the flow path. The flow path is additionally so embodied that an imaginary central axis (LB) of the intermediate region is not parallel to an imaginary central axis of the intake region and/or not parallel to an imaginary central axis of the drain region.
