摘要： The disclosure is directed to a capacitive pressure sensor, and the assembly of a capacitive pressure sensor, that may be used within an implantable medical pump. In one example, a housing ferrule that encloses one capacitive plate and includes at least one protrusion for attaching a support structure of the capacitive plate. The at least one protrusion defines a smaller inner diameter as a reference point for securing the support structure while the ferrule provides a larger inner diameter to allow the support structure to tilt inside the ferrule to orient the capacitive plate into a desired plane. Despite manufacturing irregularities, the capacitive plate can be mounted in the desired plane parallel to another capacitive plate, a diaphragm, mounted to an edge of the ferrule. In another example, an assembly tool provides a stage to orient the capacitive plate and support structure within the ferrule at a desired depth.

摘要： There is disclosed a transducer employing radiation hardened electronics. Essentially a sensor assembly is positioned in a front section of a housing where the sensor assembly is coupled to an electronic module via terminals which connect the sensor to the module. The electronic module assembly is surrounded by an internal tungsten housing which is formed from a first tungsten "U" shaped cross-sectional member coupled to a second tungsten "U" shaped cross-sectional enclosure. The two members are coupled together and totally surround the electronic assembly. The members as held together are positioned within the housing by outer shell members to form a complete housing assembly whereby the electronic assembly and its associated terminal pins are totally surrounded by the tungsten holder section and the tungsten enclosure section.

摘要： A battery powered wireless fluid pressure sensor has a sealed chamber which can be vented to the outside atmosphere through a re- sealable reference port to allow a user to set the reference atmosphere inside the pressure sensor enabling the pressure sensor to provide absolute, gauge and true gauge pressure readings. The sensor calculates and transmits the fluid pressure taking into account the temperature of the pressure transducer, the temperature of the electronic devices and the barometric pressure inside the sealed chamber to provide accurate pressure measurements over a wide range of operating conditions.

摘要： The housing (11) has a bore (41) extending therethrough communicating at its upper end with a central space (42). The housing (11) is made of a strong rigid material, preferably steel. The lower part of the housing has external threads (43) adapting the device to be screwed into a pressure manifold or other source of pressure to be detected or measured, to communicate with bore (41) and space (42) at its end. The housing (11) is also provided with a hexagonal section (45) facilitating use of a wrench for tightening the transducer in a wall of the pressure source. Extending upwardly from the threaded portion (43) is an integral outer sleeve or skirt (47) which as described below is utilized to retain parts of the assembly together. The housing (11) also has an annular seat within the sleeve (47) surrounding a coaxial annular projecting rib (51) separated from the central space (42) by an annular area (49) surrounding the space (42). Annular flat (49) rims a raised central portion (54). As is readily seen, the housing (11) is particularly adapted for simple fabrication by conventional screw machine techniques.

摘要： A transmitter (8) with a flame arresting header (16) senses a pressure of a process fluid with a diaphragm (44) which is sealed to the header. The diaphragm (44) transfers the pressure of the process fluid acting on an outer surface of the diaphragm (44) to a fill fluid (50). A pressure sensor (18) enclosed in the transmitter (8) senses the pressure of the fill fluid (50) providing an output representative of the pressure of the process fluid. The header (16) includes a chamber (48) on an outer face of the header (16) and a passageway (54) extending from the chamber (48) to a tapered opening (56) inside the transmitter (18) with a first portion (58) adjacent to the tapered opening (56) shaped to receive an inlet tube (52) sealed with a tapered seal and leading to the sensor (18) and a second flame isolating portion (70) open to the chamber (48). The second passageway portion (70) is shaped for flame isolating the tapered seal (60) from the process fluid.

摘要： A pressure transducer is provided which incoroporates numerous stress reducing characteristics. A pressure sensor is mounted to a ceramic plate (28) with a buffer plate therebetween to isolate the pressure sensor from stresses that could be transmitted through the ceramic plate. The ceramic plate (28) is necessary for the purpose of supporting a plurality of electronic components which comprise an amplification and compensation circuit. The ceramic plate (28) is separated from all parts of its housing (12) except a minimal central surface on a support boss (24) which provides the support for the pressure sensitive device (26). Electrical communication between conductive paths on the ceramic plate and terminals extending through the housing is provided by flexible electrical conductors. A cover is attached to the housing with snap acting contact which further isolate the housing from the cap. The housing (12) and cap (36) are constructed to support the housing in a noncontact association with an external device when feet on the cap are attached directly to the external device. This offset positioning of the housing with respect to the external component further isolates the housing from sources of external stress. The combined stress isolated techniques used in the present invention permit a pressure sensor to measure very low pressures with a high degree of sensitivity without introducing measurement problems that would otherwise be incumbent in this type of transducer because of externally caused stresses transmitted from external forces and originating in the transducer because of thermal stress.
