Abstract
A device is disclosed to measure the level of material within containers, in particular containers in which free-flowing materials having different dielectric constants, for example water and oil, are collected. The device includes a sensor, which is arranged electrically nonconductively fashion on an outer side of the container and forms part of an electric capacitor, and an electrically conducting complementary plate, which is arranged on the inside of container opposite the sensor and spaced therefrom, which, forms another part of an electric capacitor.
Claims3
A device to measure the level of material within a container, in particular a container in which free-flowing material having different dielectric constants is collected, said device comprising a sensor which is arranged in an electrically nonconducting manner to an outer side of the container, said sensor forming a part of an electric capacitor, and an electrically conducting complementary plate, said complementary plate being located within the container opposite the sensor and spaced therefrom, said complementary plate forming another part of the electrical capacitor, wherein the sensor comprises a housing which is at least partially electrically conducting and an electrically conducting capacitor plate which is electrically nonconducting relative to the housing.
