    摘要: A pressure detector that includes a case connectable to a flow route for liquid, and a membrane member provided in the case and with which a liquid-phase portion to be supplied with the liquid in the flow route and a gas-phase portion to be supplied with gas are separated from each other, the membrane member being displaceable in accordance with a pressure of the liquid supplied to the liquid-phase portion, the pressure detector detecting the pressure of the liquid in the flow route by detecting a pressure in the gas-phase portion. The gas-phase portion has an opening through which the gas is allowed to be introduced or discharged in accordance with the displacement of the membrane member, and a secured portion secured for the introduction or discharge of the gas through the opening during the displacement of the membrane member toward a side of the gas-phase portion.

    摘要: Modular sensor configurations utilize an embeddable sensor module configured for integration into a product or device, or a technical element thereof, for in situ sensing at least one property or condition associated with the product or device, or its technical element, or with a substance contained, processed or streamed therethrough. The embeddable sensor module includes one or more sensor elements that sense the at least one property or condition, and circuitry for generating measurement data/signals indicative of the at least one property or condition, and for transmitting the generated measurement data/signals to an external device. The embeddable sensor module can be powered and activated by signals received from an external device. Such sensing structures/arrays can utilize embeddable sensor modules integrated into a product or device and an external device configure to externally power and activate the embeddable sensor modules to cause them to generate and transmit the measurement data/signals.

    摘要: Header construction and techniques are disclosed that utilize header layers that provide support for electrical interconnections. A sensor header assembly includes: an upper header layer having upper through holes arranged in a first configuration; a lower header layer having lower through holes arranged in a second configuration axially offset relative to the first configuration; depressions extending from the lower header layer top surface and partially through the lower header layer, each depression defining a footprint corresponding to the first configuration of the corresponding upper through holes of the upper header layer; upper header pins extending through the corresponding upper through holes and at least partially into the corresponding lower level depressions; and lower header pins extending through the corresponding lower through holes and in electrical communication with the corresponding upper header pins. The depressions form support surfaces for supporting at least the corresponding upper header pins during high-pressure operation.

    摘要: An overload-resistant pressure measuring sensor includes a pressure sensor arranged in an interior of a sensor housing and can be exposed, through an opening in the sensor housing, to a medium under pressure of up to 1000 bar. The medium may be a hydrogen-containing medium and can be measured with high measurement accuracy. The pressure sensor is mounted on connection elements protruding into the interior and free-standing in the interior such that the pressure sensor is exposed to the pressure prevailing in the interior on all sides. The pressure sensor includes two ceramic measuring bodies connected to one another while enclosing a pressure chamber, and are each deformable by the pressure acting thereon, and further includes an electromechanical transducer which converts a mechanical variable that is dependent on a sum of the pressure-dependent deformations of both measuring bodies into a measurable electrical measurement variable.
