摘要： A method and an apparatus for determining or monitoring a predetermined fill level, a phase boundary or a density of a medium in a container with an oscillatable unit. The oscillatable unit is placed at the height of the predetermined fill level and is excited to oscillate successively with discrete exciter frequencies following one another in a frequency scanning operation (sweep) within a predeterminable frequency band in the working range of the oscillatable unit. The corresponding oscillations of the oscillatable unit are received in the form of received signals; wherein that exciter frequency is ascertained in the frequency scanning operation, at which the oscillatable unit oscillates with an oscillation frequency, which has a predetermined phase shift between the transmission signal and the received signal; and wherein the transmitting/receiving unit excites the oscillatable unit to oscillate with the ascertained oscillation frequency.

摘要： Field device for determining or monitoring a physical or chemical process variable, wherein the field device is composed of a sensor, which works according to a defined measuring principle, and a control/evaluation unit, which, as a function of a safety standard required for the particular safety-critical application, conditions and evaluates, along at least two equivalent measuring paths, measurement data delivered by the sensor. The control/evaluation unit is implemented on an FPGA, on which are provided at least a first section and a second section, wherein, in each section, a digital measuring path, which is composed of a plurality of software-based and/or hardware-based function modules, is dynamically reconfigurable. The sections are isolated from one another by permanently configured spacer regions, wherein the spacer regions are embodied in such a way, that a temperature and/or a voltage change in one of the sections has no influence on the other section or other sections, and, in the case of malfunction, no connection occurs between the sections. The control/evaluation unit, as a function of the particular defined safety-critical application, partially dynamically reconfigures the function modules in the measuring paths in such a manner, that the field device fulfills the required safety standard.
