    Abstract: A pressure detection device including a mount whereon a pressure sensor is attached which comprises a membrane which has a surface intended to be subjected to a pressurized fluid and which is so arranged as to elastically deform according to pressure, and means for determining the deformation of the membrane along an axis normal to a mid-plane of the membrane in the rest state. The membrane is supported by a frame connected to the mount by a mechanical decoupling structure in order to isolate the membrane from stress resulting from a differential thermal expansion between the frame and the mount, with the membrane and the frame being made of the same material.

    Abstract: A pressure sensor includes a tubular housing; a diaphragm which is joined to one end portion of the housing through a fusion zone; and a sensor element which is disposed in the housing and to which pressure received by the diaphragm is transmitted. As viewed in a section which contains the center axis of the housing, a pair of the fusion zones exist, and each of the fusion zones is formed in such an inclined manner that its distance from the center axis increases as it extends from the outer surface of the diaphragm toward the other-end-portion side of the housing.

    Abstract: A pressure sensor apparatus is provided. The pressure sensor apparatus includes a bottom plate, a pressing interface opposite to the bottom plate, elastic connectors disposed between the bottom plate and the pressing interface and connecting the bottom plate and the pressing interface, a piezoelectric sheet, a drive member abutted against the piezoelectric sheet and the pressing interface and a processor module. When the pressing interface is pressed, the compression elastic connectors can be deformed; the drive member can transmit the deformation to the piezoelectric sheet so that the piezoelectric sheet can be deformed and then output an electrical signal, and the processor module can calculate the degree of the pressing force exerted onto the pressing interface based on the electrical signal outputted by the piezoelectric sheet and choose corresponding programs based on the association relationship information between the predefined degree of pressing force and the programs.
