    摘要： The application provides a gas density relay with online self-check function and its check method, including a gas density relay body, a first pressure sensor, a second pressure sensor, a temperature sensor, a gas chamber, a pressure regulating mechanism, an online check contact signal sampling unit and an intelligent control unit. The air path of the pressure regulating mechanism is connected to the gas pressure chamber and the second pressure sensor; Pressure rise and fall can be regulated through the pressure regulating mechanism to make the gas density relay body contact action. The contact action is transmitted to the intelligent control unit through the online check contact signal sampling unit. The intelligent control unit detects the action value and/or return value of the contact signal of the gas density relay body according to the density value when the contact acts, and completes the check work without requiring maintainer to go to the site for check. At the same time, because the pressure regulating mechanism is not connected to the SF6 gas path of the gas density relay body or electrical equipment, its sealing requirements are reduced, the reliability of the power grid is improved, and the manufacturing cost is reduced.

    摘要： An apparatus for controlling blending of a gas mixture containing known components, including first, second, and third control valves for controlling the flow of first, second, and third components, respectively, a first gas density sensor to measure the density of a first mixture of the first and second components, a second gas density sensor to measure the density of a second mixture of the first mixture and the third component, and a controller to determine based on data from the first and second gas density sensors the relative compositions of the first, second, and third components in the second mixture, and to control the first, second, and third control valves to obtain a desired relative composition of the first, second, and third components in the second mixture.

    摘要： The present disclosure provides a method for modifying a gas density relay and a gas density relay having an online self-check function and a check method therefor. The gas density relay having an online self-check function is used for high-voltage and medium-voltage electrical devices, and includes a gas density relay body, a gas density detection sensor, a gas path blocking pressure regulation mechanism, an online check contact signal sampling unit and an intelligent control unit. The intelligent control unit controls a blocking member of the gas path blocking pressure regulation mechanism to move, so as to block a gas path between a first interface and a second interface. Moreover, a volume of a sealed cavity changes, a gas pressure of the gas density relay body slowly falls, thereby generating contact action, the contact action is transmitted to the intelligent control unit by means of the online check contact signal sampling unit, and the intelligent control unit detects an alarm and/or blocking contact signal action value and/or return value according to a density value during the contact action, such that check can be completed without maintenance personnel on site, and the reliability and efficiency of a power grid are greatly improved while cost is lowered.

    摘要： Components and systems are disclosed for determining fluid component concentrations. In some embodiments, a vortex chamber is configured to rotationally direct fluid flow. A first pressure sensor is disposed on an inner radial position within the vortex chamber. A second pressure sensor is disposed on an outer radial position within the vortex chamber. A fluid property detector is configured to determine a fluid property based, at least in part, on pressure values detected by the first and second pressure sensors.

    摘要： The method for determining density of fresh concrete inside a drum of a mixer truck involves a probe mounted inside the drum, extending in a radial orientation of the drum and being moved circumferentially as the drum rotates. The method has: receiving first and second pressure values indicative of normal pressures exerted on the probe by the fresh concrete at corresponding and different first and second circumferential positions of the drum during rotation of the drum; and determining a density value of the fresh concrete based on the volume of the probe and on a difference between the first and second pressure values.
