摘要： A pressure sensor has a pressure responsive capacitor electrically connected to a signal conditioning circuit which is calibrated after mounting in a housing to provide an electrical signal corresponding to an applied pressure. The capacitor has thin metal capacitor plates on facing surfaces of a ceramic diaphragm and base and is adapted to receive an applied pressure on the diaphragm. Terminals from the capacitor are disposed on an opposite surface of the capacitor base; the circuit has a flexible substrate having a first end overlying the opposite base surface mounting circuit components electrically connected to the capacitor terminals and has an opposite end folded over the first end electrically connected to connector terminals on a connector body overlying the base; and the housing includes a metal sleeve fitted over the capacitor and body having a rim clamping the capacitor and connector body together to form the sensor. The connector body has a tubular portion open at both ends accessible from outside the body and extending to the flexible circuit to permit circuit calibration through the tubular portion and has an encapsulant therein sealing the body after calibration. Circuit pads capacitively coupled to ground connections at each end of the flexible circuit substrate are provided on substrate tabs which extend between the body and housing rim to be clamped in electrical engagement to each other and to the housing to provide improved electromagnetic compatibility for the sensor.

摘要： A fluid pressure sensor particularly useful for measuring pressure up to approximately 2000 psi has a hexport (12, 112, 212, 312) formed with a stop surface (26, 326) in a bottom wall (18) circumscribing a fluid pressure inlet (16). A pressure sensing module (22) is received on the stop surface and a distal end (40) of a wall (20, 120, 320) of the hexport is crimped to lock the pressure sensing module onto the stop surface with the stop surface limiting the amount of compression of an O-ring (30) disposed contiguous to and inboard of the stop surface. In one embodiment the crimp is placed directly on a metal ring (38) attached to a plastic connector (32) which in turn transfers the crimping force to the pressure sensing module. In other embodiments (FIGS. 2, 3) the crimp is placed directly in the pressure sensing module to form a subassembly. In one embodiment, a separate sleeve (142) member connects the subassembly to the plastic connector while in another embodiment the connector is provided with an extended skirt which snaps over the hexport to connect the connector to the subassembly. In yet another embodiment, the plastic connector (332) is formed with a strengthening flange (334) received around the pressure sensing module and the crimp is formed directly on the plastic connectors to reduce contact stresses in the crimp and compensate for crimp wall springback.

摘要： A pressure transducer having a pressure sensing surface spaced from an interior surface of the transducer housing by a relatively rigid back-up ring which contacts each of the pressure sensing surface, the interior surface of the housing and an interior side wall of the housing. A relatively less rigid O-ring is disposed between the pressure sensing surface and the interior surface of the housing and contacts the back-up ring, the back-up ring and the O-ring providing sealing of the pressure cavity. The O-ring communicates with the fluid entering the housing via an inlet in the housing. Because the output of the pressure sensing element is affected by the loading of the O-ring and back-up ring, and because this loading changes over time, mainly due to cold flow, compression set, etc.), several special procedures are provided during manufacture and before calibration of the transducers to minimize this problem to avoid calibration change (drift) over time, these being conditioning or burning in prior to calibration. This is accomplished by an extended high temperature soak through a series of pressure cycles or overpressure cycles or a combination thereof and permits the back-up ring and the O-ring to be relieved of stresses so that they will be stable over time.

摘要： A cover for an automotive vapor canister has a heat-spreading member heated by a self-regulating electrical resistance heater of positive temperature coefficient of resistivity for heating air which is periodically introduced into the canister for purging the canister. The cover has a first cover means of thermally insulating material defining a thin inner air flow path section to pass air being introduced into the canister over the heat-spreading member for transferring heat to the air and to receive additional heat within the first cover means and has a second cover means of thermally insulating material defining a thin outer air flow path section overlying and connected with the inner air flow path section to pass the air over the first cover means prior to being advanced into the inner flow path section for withdrawing said additional heat from the first cover means to preheat the air and improve air heating efficiency.

摘要： The disclosure relates to a pressure transducer for use in measurement of pressures in the range of 3000 to 5000 psi and above wherein the pressure sensing module is physically separated from the electrical connector by a barrier formed from a material which is less readily deformable under high pressure than the connector. This is accomplished in one embodiment by separating the electrical connector from the pressure sensing element by a metal support ring againsst which the pressure sensing element bears. In accordance with a second embodiment, the electrical connector is disposed externally of the housing with the pressure sensing element being disposed within the housing and bearing against an interior wall thereof. In accordance with a third embodiment, the housing is formed of two inexpensive members, one crimped within the other, with the pressure sensing module bearing against an interior wall of the inner housing member and the connector being crimped to the system by a flange on the outer housing member. Preferably, a conductor, which is connected to the circuit ground of the electronic circuitry is also coupled to the system ground by crimping it between the housing and the electrical connector during the crimping of the connector to the remainder of the transducer.
