摘要： A relative-pressure sensor for determining a pressure of a medium in relation to an atmospheric pressure includes a housing; a measuring element arranged in the housing, wherein the pressure to be measured acts upon an outer surface of the measuring element in contact with the medium; a reference-pressure supply, which supplies an inner surface of the measuring element with atmospheric pressure in the form of ambient air, an evaluation unit, which determines the pressure of the medium from a variable determined using the measuring element; and at least one drying chamber arranged in the housing for taking up atmospheric humidity from the ambient air supplied through the reference-pressure supply. A bushing can be pressed into the housing and has a capillary-type groove, which is helical at least in sections and runs around the bushing.

摘要： A sensor includes an airfoil body, a heater element, and a temperature probe. The airfoil body defines a sensor axis, an insulating cavity, and extends between a leading edge and a trailing edge of the airfoil body. The heater element extends axially within the airfoil body and is positioned between the leading edge and the trailing edge of the airfoil body. The temperature probe extends axially within the airfoil body, is positioned between the heater element and the trailing edge of the airfoil body, and is separated from the heater element by the insulating cavity to limit thermal communication between the temperature probe and the heater element. Gas turbine engines, methods of making sensors, and methods of thermally separating temperature probes and heater elements in sensors are also described.

摘要： A sensor device is constructed to maintain a high glass strength to avoid the glass failure at low burst pressure, resulting from the sawing defects located in the critical high stress area of the glass pedestal as one of the materials used for construction of the sensor. This is achieved by forming polished recess structures in the critical high stress areas of the sawing street area. The sensor device is also constructed to have a robust bonding with the die attach material by creating a plurality of micro-posts on the mounting surface of the glass pedestal.

摘要： A microelectromechanical pressure sensor structure that comprises a planar base and side walls and a diaphragm plate. The side walls extend circumferentially away from the planar base to a top surface of the side walls. The planar base, the side walls and the diaphragm plate are attached to each other to form a hermetically closed gap in a reference pressure, and a top edge of the inner surfaces of the side walls forms a periphery of a diaphragm. The diaphragm plate comprises one or more planar material layers of which a first planar material layer spans over the periphery of the diaphragm. The top surface of the side walls comprises at least one isolation area that is not covered by the first planar material layer.
