    摘要: The device includes a distal connector portion with a connector for electrical connection to an external electrical circuit, a proximal measuring portion including a detector of the physical parameter configured to be in fluid contact, the detector has a general shape of a wafer delimiting a first electrical contact face and a second opposite measuring face, a member for electrically joining the detector and the connector. The detector is configured in the device such that both faces of the detector are immersed and in direct fluid contact.

    摘要: The present invention provides a pressure sensor module capable of improving work efficiency during assembly.
    The pressure sensor module detects a fluid pressure on the basis of a differential pressure between a reference pressure and the fluid pressure, and includes: a housing; a sensor element that can contact each of the reference pressure and the fluid pressure; a support member that supports the sensor element and is held in the housing; a first pressure passage that guides the fluid pressure to a first contact surface of the sensor element; and a second pressure passage that is sealed from the first pressure passage and guides the reference pressure to a second contact surface of the sensor element. The support member is a structure that is formed by integrating an elastic material section exerting sealing performance on the first pressure passage and the second pressure passage and capable of being elastically deformed and a hard material section, rigidity of which is higher than the elastic material section.

    摘要: A manifold assembly configured to measure differential pressure of fluid. The manifold assembly may have a monolithic body with an internally drilled fluid pathway. The body supports a differential pressure transducer that communicates, on either end, with the internally drilled fluid pathway. This configuration can generate data that defines pressure drop across impellers or other mechanisms on metrology hardware (or “gas meters”). Utilities can use this data to diagnose health or other conditions on the gas meter in the field.

    摘要: An intravascular pressure sensor assembly is disclosed herein that is produced in part using photolithography and DRIE solid-state device production processes. Using DRIE production processes facilitates a number of features that could not be readily incorporated in sensor chips fabricated using mechanical saws. In accordance with a first feature, sensor chips are created with non-rectangular outlines. The sensor chip includes a widened portion that substantially abuts an inner wall of a sensor housing, and a cantilevered portion that is relatively narrow in relation to the widened portion. The non-rectangular outline of the sensor chip is formed using photolithography in combination with DRIE processing. In accordance with another feature, the sensor chip is positioned width-wise in the housing, thereby reducing a required length for the housing. In accordance with yet another feature, the sensor chip comprises one or more cutouts for receiving signal wires for connection to signal lead lines on the sensor chip. The outline of the sensor chip and the cutouts are formed using photolithography in combination with DRIE processing.

    摘要: There is provided a sensor device for measuring fluid and fluid conduit properties, and a method for activating the sensor device. The sensor device comprises an outer capsule for providing fluid-tight containment to an interior compartment of the sensor device in a closed position. The outer capsule comprises a first capsule portion and a second capsule portion. An aperture is located in the second capsule portion and fluidly connects the inner compartment to an exterior of the outer capsule. A mounting bracket is disposed within the inner compartment, the mounting bracket connects the first capsule portion to the second capsule portion and provides structural integrity and pressure resistivity for the outer capsule. At least one pressure sensor is constrained between the mounting bracket and an inner surface of the second capsule portion and is aligned with the aperture of the second capsule portion.

    摘要: A pressure testing module separable from and configured to be coupled with a tool base that is to be coupled along a downhole tool string to be conveyed within a wellbore extending into a subterranean formation. The pressure testing module includes a chamber and a piston assembly slidably disposed within the chamber, thus dividing the chamber into a first chamber portion and a second chamber portion. The piston assembly is operable to move in response to hydraulic fluid being pumped into the first chamber portion and to draw formation fluid of the wellbore into the second chamber portion in response to the movement of the piston assembly.
