    摘要: A monolithic capacitive differential pressure transducer (10, 44,) is shown composed of ceramic material having first and second cavities formed adjacent to opposed face surfaces to form first and second flexible diaphragms (12, 14; 50, 52) and a motion transfer pin (24, 58) attached to and extending between the diaphragms. Capacitor plates are disposed on a surface of at least one flexible diaphragm and a stationary member to form a capacitive gap. Component parts are first pressed from ceramic powder and assembled into a unit using one of several methods including relatively high pressure to press them together or using a combination of low pressure along with raising the temperature of the material to soften the binder in the ceramic material at surfaces of the parts which are to be joined together. Selected gaps, both along the x-y direction and along the z direction may be obtained, particularly in assembling the parts using high pressure using consumable spacer material which is sublimated in a debinderization cycle prior to sintering of the unit to form a monolithic body.

    摘要: An acceleration sensor is shown having a substrate (16, 16', 16", 16'") on which a capacitor detect plate (24) and source plate mounting portion (28c) are disposed. An electrically conductive blade member (40, 44) having an attachment portion (40a, 44h), a source plate portion (40i, 44a) and integrally attached beams (40b, 40c; 44b) extending along opposite sides of the blade member is mounted on the substrate by welding the attachment portion to a mounting element (36, 36', 36", 36'") which is closely received in a bore (32, 32', 32", 32'") formed through the substrate at the source plate mounting portion. The mounting element or the bore is formed with a surface suitable for forming an interference fit and for making electrical engagement with a conductive layer received in the bore. The mounting element has one end (36b, 36b', 36b") which extends above the top surface (26, 26") an adjustable selected amount(s) to provide desired spacing between the source plate portion and the detect plate. A single mounting element of a pair of mounting elements can be used and may be in the form of a solid (36, 36", 36'") or a hollow (36') pin.

The metal blade member (24) is mounted on the substrate (18) so that the source plate portion is a selected distance from a detect plate (18b) mounted on the substrate. The sensor is disposed in a cylindrical housing (12, 12', 12") which can be directly mounted to a circuit board (50) through terminal pins (18g, 18h, 18i) or can be provided with a threaded fastener (12"d). In one embodiment first and second sensor modules are received in a housing (42) to sense acceleration forces in two perpendicular directions. In another embodiment tab (30b) extending from a signal conditioning circuit (30) is placed between a connector body (20') and the sidewall (12b) of housing (12) with a detent (12c) formed in the sidewall (12b) to effect an electrical connection between circuit (30) and housing (12"). An O-ring gasket (13) is placed between the sidewall (12b) and the connector body (20') outboard of the detent to provide an environmental seal.

    摘要: An accelerometer unit has a capacitor detect plate and a source place connector preferably defined respectively inside and outside a groove in one surface of a ceramic substrate. A flat metal member has an attachment portion secured in electrically conductive relation to the connector, has a source plate portion spaced over the detect plate to form a capacitor, and has integral resilient beams extending from the attachment portion to support the source plate portion spaced from the detect plate to be movable relative to the detect plate in response to acceleration force to provide an electrical signal. Preferably glass rods between the attachment member portion and source place connector facilitate the spacing. An electrically insulating housing base has integral pins extending through openings in the accelerometer unit substrate and in a separate electrical circuit unit to mount the circuit unit in spaced, overlying relation to the accelerometer unit, and an electrically conductive adhesive extends through guide holes in a gasket between the accelerometer and circuit units to electrically connect the circuit to the detect plate and to the connector on the ceramic substrate.
