  • Publication number: 20190049282
    Abstract: A sensor array for a potentiometric measurement of a fill level in a container. The sensor array includes an electro-magnetically shielding array whose potential is dependent on a potential of the container, and an oscillator array which generates an AC voltage. The oscillator array is at least partly arranged in the electro-magnetically shielding array.

  • Publication number: 20120268139
    Abstract: In order to provide a device (1) for detecting a level (3) of media (4), preferably in a tank (2, 200), comprising an elongate electrical probe conductor (6) projecting substantially vertically into the tank (2, 200), which can be attached in a manner electrically insulated from said tank, a electrical time-variable generator (7) having an internal impedance (Zg) for connection to a feed point (11) of the probe conductor (6) in order to apply a time-variable voltage to this, wherein the feed point (11) is disposed on one, preferably on the tank-side, end of the probe conductor (6), and an evaluation and/or control unit (9) for evaluating an electrical quantity of the probe conductor (6), which can detect a level of any media, in particular liquid, pasty and/or granular solid media, in the simplest possible, error-tolerant and cost-effective manner, it is proposed that the evaluation and/or control unit (9) is configured to measure a base impedance of the probe conductor (6) at the feed point (11).

  • Patent number: 5983716
    Abstract: The invention covers a procedure for measuring hydrostatic pressure, especially that of ground water, with the particularity that air is bubbled into the ground water, the pressure in the measuring pipe is fed to an absolute pressure cell and atmospheric pressure is then applied to the same measurement cell.
