摘要： A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.

摘要： A pressure sensor including a housing extending along an axial line, a diaphragm fixed to a front-end side of the housing, a piezoelectric unit disposed in a hole in the housing and including a piezoelectric element, a transmission member that transmits deformation of the diaphragm to the piezoelectric unit, and a guide member having a through hole extending along the axial line and surrounding the piezoelectric unit in the through hole. (SL/AL)≤0.26 is satisfied in the cross section perpendicular to the axial line passing through the piezoelectric element, where SL is the maximum value of the distance in the radial direction between the center of the through hole and the center of the piezoelectric element and AL is the maximum value of the distance in the radial direction between the outside surface of the piezoelectric element and the center of the through hole.

摘要： Provided is a composition for bonding that forms, after bonding, an adhesive layer that is less likely to undergo shape deformation, and can maintain high adhesion after a reliability test; also provided are an optical adhesive and an adhesive for pressure sensors, both of which comprise the composition. The composition for bonding comprises resin particles. The resin particles have a recovery rate of 20% or less, and a cured product of the composition with a thickness of 250±50 μm has a moisture permeability of 90 g/m2-24 h or less. An adhesive layer formed from the composition for bonding is less likely to undergo shape deformation, and can maintain high adhesion after a reliability test.

摘要： A pressure-sensor device (1) comprises: a pressure-sensitive component (5, 5a, 6), having a sensor body (5) that includes an elastically deformable membrane part (5a) and at least one detection element (6) suitable for detecting a deformation of the membrane part (5a); a supporting structure (2, 3) for supporting the pressure-sensitive component (5, 5a, 6), having a passageway (15) for a fluid of which a pressure is to be measured. The supporting structure (2, 3) comprises: a supporting body (2) with respect to which the sensor body (5) is positioned in such a way that its membrane part (5a) is exposed to the fluid exiting the passageway (15), the supporting body (2) having at least one through cavity (14), a compressible body (16), which is configured for compensating possible variations of volume of the fluid. The supporting body (2) has a first body portion (2c) comprising a transverse wall (22) of the through cavity (14), defined in which is at least one first passage (23a-23b) and at least one second passage (24), the at least one first passage (23a-23b) belonging to the passageway (15) for the fluid. The compressible body (16) is an element over-moulded with respect to the supporting body (2), that has respective opposite portions (20, 21) which extend in positions corresponding to opposite sides of the transverse wall (22), and which are connected to one another via at least one intermediate portion (16a) of the compressible body (16) that that extends through the at least one second passage (24). The first body portion (2c) is shaped to define at least one step or one projection or one relief (25; 28) which determines at least one of: a cross-sectional narrowing of the at least one second passage (24), configured to define a corresponding cross-sectional reduction of the at least one intermediate portion (16a) of the compressible body (16), and a development of the at least one intermediate portion (16a) of the compressible body (16) which is generally tortuous or comprises a number of stretches substantially angled to each other.

摘要： An apparatus including a first linear contact, a second linear contact and a support contact. The first linear contact and the second linear contact may each be connected to corresponding electrical terminals. The support contact may be connected to a housing. The first linear contact and the second linear contact may each provide an electrical connection between corresponding sensor contacts and the corresponding electrical terminals. The first linear contact, the second linear contact and the support contact may be arranged to create a support plane for a sensor package. The first linear contact and the second linear contact may each provide support for the sensor package along a linear peak. The apparatus may enable a secure compression fit of the sensor package within the housing.

摘要： A method and structure which provide an ambient pressure measurement that is unaffected by wind and localized environmental conditions. A draft range pressure transmitter is enclosed inside an enclosure which is resistant to wind and other transient localize environmental conditions. A vent cap allows slow air movement through a wall of the enclosure and forms a still air chamber for the transmitter. The pressure inside the enclosure changes at the same rate as the barometric pressure but is unaffected by wind or wind gusts.

摘要： Microphones including a housing defining a cavity, a plurality of conductors positioned within the cavity, at least one dielectric bar positioned within the cavity, and a transducer diaphragm. The conductors are structured to move in response to pressure changes while the housing remains fixed. A first conductor generates first electrical signals responsive to the pressure changes resulting from changes in an atmospheric pressure. A second conductor generates second electrical signals responsive to the pressure changes resulting from acoustic activity. The dielectric bar is fixed with respect to the cavity and remains fixed under the pressure changes. The dielectric bar is adjacent to at least one of the conductors. In response to an applied pressure that is an atmospheric pressure and/or an acoustic pressure, the transducer diaphragm exerts a force on the housing and displaces at least a portion of conductors with respect to the dielectric bar.
