A pressure sensor arrangement includes a tube with a diaphragm to pressure to be measured is applied arranged in the cross-section of the tube, wherein the diaphragm is fastened to the tube inner wall via an articulation extending along the circumferential region of the diaphragm, where deformation of the diaphragm results in rotation of the articulation directly on the wall of the tube which can therefore be detected from the outside by suitable structure such that that strain sensors, for example, which can be used to detect deformation are advantageously not in contact with the process medium and there is advantageously no need for a pressure-tight bushing for electrical signals, and where the pressure sensor arrangement has a particularly simple structure and can be advantageously used in measuring transducers for process instrumentation.

An apparatus for producing strain in an optical fibre proportional to dynamic pressure fluctuation in the surrounding substance. The apparatus includes a diaphragm having a first face that, in use, is exposed to dynamic pressure fluctuations in the substance, and a second, opposite face, the diaphragm being adapted to flex in response to dynamic pressure fluctuations applied to it. One or more optical fibres are mounted on either the first or the second face of the diaphragm, whereby strain is produced in the fibre when the diaphragm flexes.

The first arm actuators and the second arm actuators are operable to wrap the first arm and the second arm around an object and hold the object against the body structure. The tilt structure is operable to tilt the body structure. The lift actuator is operable to move the body structure such that the object is lifted.

A pressure sensor device includes a base layer, a deformable layer bonded to the base layer such that the base layer and the deformable layer define at least one inflatable chamber, and at least one pressure sensor fluidly coupled to the at least one inflatable chamber and operable to produce a signal indicative of a pressure within the at least one inflatable chamber.

An MEMS pressure sensing element is disclosed, comprising a substrate with a groove; a pressure-sensitive film on the substrate for sealing an opening of the groove to form a sealed cavity body; and a pressure-sensitive beam suspended in the sealed cavity body and parallel with the pressure-sensitive film provided with varistors, wherein a center of the pressure-sensitive beam is fixedly connected to that of the pressure-sensitive film, and a periphery is fixedly connected to a bottom wall of the groove of the substrate, such that the pressure-sensitive film drives the pressure-sensitive beam to bending deformation under an external pressure.

A pressure sensor arrangement includes a tube with a diaphragm to pressure to be measured is applied arranged in the cross-section of the tube, wherein the diaphragm is fastened to the tube inner wall via an articulation extending along the circumferential region of the diaphragm, where deformation of the diaphragm results in rotation of the articulation directly on the wall of the tube which can therefore be detected from the outside by suitable structure such that that strain sensors, for example, which can be used to detect deformation are advantageously not in contact with the process medium and there is advantageously no need for a pressure-tight bushing for electrical signals, and where the pressure sensor arrangement has a particularly simple structure and can be advantageously used in measuring transducers for process instrumentation.

A process fluid pressure transmitter is provided. The process fluid pressure transmitter includes a pressure sensor having an electrical characteristic that changes in response to a deformation of the pressure sensor in response to pressure. Measurement circuitry is coupled to the pressure sensor and is configured to provide an indication of the electrical characteristic. An isolation diaphragm is configured to contact the process fluid and deform in response to process fluid pressure. A substantially incompressible fill fluid fluidically couples the isolation diaphragm to the pressure sensor. An overpressure compliant structure is coupled to the fill fluid and is configured to be substantially rigid at pressures below a selected threshold, but to deform in response to pressure above the selected threshold.
