摘要： An apparatus includes a sensor body and a sensor configured to measure pressure. The apparatus also includes at least one pressure input in or on the sensor body, where the at least one pressure input is configured to provide at least one input pressure to the sensor. The apparatus further includes multiple fluid passages configured to convey the at least one input pressure from the at least one pressure input to the sensor using a fill fluid. The multiple fluid passages are configured to both (i) transport the fill fluid and (ii) absorb thermal energy in a flame created by the sensor before the flame exits the sensor body. The fluid passages can include long and narrow straight passages, long and narrow curved or helical passages, and turns or bends. The fluid passages can have small cross-sections relative to their lengths.

摘要： An apparatus includes a sensor body and a sensor configured to measure differential pressure. The apparatus also includes first and second coplanar pressure inputs in or on the sensor body, where the pressure inputs are configured to provide multiple input pressures to the sensor. Each pressure input includes a barrier diaphragm configured to move in response to pressure and an overload diaphragm configured to limit movement of the barrier diaphragm. First and second fill fluid may be configured to convey the pressures from the barrier diaphragms of the pressure inputs to the sensor as first and second input pressures. Passages may be configured to transport the fill fluid between (i) gaps between the barrier diaphragms and the overload diaphragms of the pressure inputs and (ii) the sensor and gaps between the overload diaphragms and the sensor body.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An oil-filled pressure transducer having reduced back pressure, comprising an alignment plate having a sensor accommodating aperture, a sensor module inserted into the sensor accommodating aperture, a header surrounding the alignment plate, the header having a protruding top surface, and a diaphragm disposed on the protruding top surface to create a relatively small oil accommodating region between the diaphragm and the sensor. This configuration reduces the oil volume required for operation, which ultimately reduces the back pressure applied against the diaphragm.
