摘要： A sensor assembly (40) comprising a sensor die (42) including a first member (44) and a second member (46). The first member (44) comprises a diaphragm (54) extending between first and second opposed surfaces (50, 48) of the first member (44). A number of electrical sensing elements (58) are disposed within the first member (44) and positioned adjacent the diaphragm (54) along the first surface (50). The second member (46) is attached with the first member (44) along the first surface (50) comprising the electrical sensing elements (58). The second member (46) has a recessed section (75) forming cavity (76) with the first member (44) to accommodate deflection of the diaphragm (54). The first member (44) includes an actuation element (47) that extends outwardly from the second surface (48) and that is positioned directly on the diaphragm (54). The sensor assembly (40) includes metallic connectors (56) and contacts (60) for facilitating connection between the electrical sensing elements (58) and an outer surface (66) of the sensor die to provide a surface mount electrical connection of the sensor assembly (40).

摘要： A stator winding temperature sensor including at least one sensing wire for connecting to a stator. The sensor also includes a body, including a core material comprising a polyimide substrate having an acrylic adhesive surrounding at least a portion of the sensing wire, and a laminate material over the core material. The body has a thickness adapted to protect the sensing wire. The sensor includes a lead wire for connecting to an external monitoring device. The sensing wire is electrically connected to the lead wire at a lead step portion of the sensor. The sensor further includes a tab extending from the lead wire and encompassing the lead step, the tab including a flexible zone where the tab is surrounded by a polyimide and an adhesive but is not surrounded by fiberglass.

摘要： An optical spectral sensing device for determining at least one property of a fluid. The device has an elongated porous body, a first end and a second end, a solid-state optical emitter at the first end of the body oriented to emit radiation toward the second end of the body, and a solid-state optical detector at the second end of the body oriented to detect radiation emitted by the optical emitter. A package for detecting properties of a fluid includes a body defining a cavity, with a movable and biased carrier for an optical detector or emitter mounted in the cavity for increased reliability. A system for determining relative concentrations of fluids in a sample includes emitter/detector pairs operating at reference wavelength and wavelengths corresponding to absorption peaks of at least two fluids, and a processor for determining concentration based on measured data and calibration data.

摘要： A low-pressure transducer including a disc-shaped metal diaphragm to which a fluid pressure is applied, wherein the diaphragm contains a raised beam formed by thinning the entire exterior surface of the diaphragm except for the beam; and at least one silicon strain gage glass bonded to the beam, wherein the low-pressure transducer can accurately gage pressures at least as low as 15 psi. The present invention also comprises a method for manufacturing a pressure transducer including the steps of forming a cylindrical diaphragm having a top surface and a lower surface; establishing a diameter and a thickness of the diaphragm relative to an operational plane by a creating a hole axially through the transducer body that terminates at the lower surface; and creating a raised surface in the shape of a cross beam integral to the operational surface; and bonding one or more strain gages thereupon.
