摘要： A level switch detects the fill level of a medium in a container and transmits a switch signal corresponding to the detected level. The level switch incorporates a signal generator for generating an electromagnetic signal, a measuring circuit, and a reference circuit into which the electromagnetic signal can be fed. The measuring circuit is so configured and positioned that the signal fed into the measuring circuit changes as a function of whether or not the measuring circuit is surrounded by the medium, while the reference circuit is so configured and positioned that the signal fed into the reference circuit remains unaffected by the fill level of the medium. A tap at a specific point on the measuring circuit collects the measuring voltage, a tap at a specific point on the reference circuit collects a reference voltage, and a voltage comparator compares the measuring voltage with the reference voltage and emits a comparison-derived switch signal. This permits the dependable detection of a specific level of the medium in the container while essentially eliminating errors due to changes in extraneous parameters such as temperature fluctuations. A method for detecting the fill level of a medium in a container employing the switch is also disclosed.

摘要： A method for measuring the fill level of a medium in a container by applying the radar principle, whereby a measuring signal is generated and transmitted in the direction of the medium. A retroreflected portion of the measuring signal is captured and the fill level is determined as a function of the runtime of the measuring signal. The measuring signal is transmitted into multiple mutually different regions and the retroreflected portions of the measuring signal is received at multiple receiving points. In this fashion, it is possible to at least approximate the surface structure of the medium in the container.

摘要： A process for measurement of the level of a medium in a container based on the radar principle in which a measurement signal is generated and emitted in the direction of the medium, the portion of the measurement signal which has been reflected back is detected and the level determined from the propagation time of the measurement signal. The portion of the measurement signal which has been reflected back is evaluated in a phase-sensitive manner in order to assign the respective level corresponding to the propagation time of the measurement signal to a specific direction of space. Thus, the level is determined even under difficult conditions, such as when structures or devices are present in the container or when loose bulk materials are present in loose bulk cones.

摘要： A radar fill-level sensing device has a high-frequency unit that serves to generate and process radar signals of a predefined frequency and wavelength, an antenna for transmitting and/or receiving the radar signals, as well as circuitry, provided on a circuit board. That circuitry includes a microstrip circuit for connecting the high-frequency unit to the antenna, that microstrip circuit featuring a ground conductor. The ground conductor encompasses a first segment, a radial stub and a second segment, the length of the first segment corresponding essentially to one quarter of the predefined wavelength. The radial stub is positioned at the end of the first segment, the second segment connects to the end of the first segment and to the radial stub, and the second segment is grounded. Based on this design, a radar fill-level sensing device is obtained that can easily and reproducibly be implemented within the requirements of “intrinsically safe” ignition protection.
