Abstract: A fill level measurement device senses the fill level of an object within a container. A fill level measurement sensor provides a sensed fill level signal indicative of the level within the container. A signal processing device is responsive to the sensed fill level signal and includes a first removable and replaceable component that includes a first memory device. The signal processing device also includes a second removable and replaceable component that includes a second memory device containing component customer parameter data. The second removable and replaceable component transmits the component customer parameter data to the first removable and replaceable component via a data link that electrically isolates the first and second removable and replaceable components, and the first removable and replaceable component stores the received component customer parameter data into the first non-volatile memory device.

Abstract: 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.

Abstract: A sensor according to the invention has an amplifier that is capacitively loaded vis-à-vis the ground by a container and by a medium contained therein and that has a capacitive feedback that is dimensioned in such a way that the amplifier only oscillates when the critical filling level has not been reached. According to the invention, the capacitive feedback is influenced by the container in such a way that the capacitive load of the amplifier input caused only by the container is countered. In this manner, it is achieved that the sensor responds only to the capacitance of the medium, largely independently of the magnitude of the container capacitance. A sensor according to the invention is also characterized by such an operating frequency that, on the basis of the conductivity of the medium, it is possible to distinguish between a massive and an apparent filling of the container with the medium simulated by wetting or foam formation, but it largely avoids those problems encountered with sensors having a very high operating frequency of more than 50 MHz.
