An electronic device for a level measurement probe for measuring a level of a medium is provided, including: at least one first excitation electronic device configured to emit a first excitation signal; and at least one second excitation electronic device configured to emit a second excitation signal, the first excitation signal and the second excitation signal being different, and the electronic unit being configured to emit the first excitation signal and the second excitation signal simultaneously to the level measurement probe.

Electronic unit for a fill level measuring probe

A sensor device for process variable determination in an industrial environment, comprising a sensor base and a first expansion module. The sensor base includes circuitry that determines the process variable, a first mechanical interface for mechanically accommodating a first expansion module and a first communication interface to the first expansion module for transmitting measurement and/or control data. In this case, the first expansion module has a second mechanical interface to the sensor base, a third mechanical interface for mechanically accommodating a second expansion module, a second communication interface to the sensor base for transmitting measurement and/or control data, and a third communication interface to the second expansion module for transmitting measurement and/or control data.

A measuring device is provided. The measuring device includes a sensor unit configured to detect a measurement signal, upstream measuring device electronics that include a signal processing circuit and an input interface, and a power limitation circuit arranged to limit the power supplied by the external power supply at the input interface.

Fill level sensor with power limitation

Described is a process measurement device having an interface for connecting a plug-in memory, in which a processing measurement device includes a memory operating device that can switch the process measurement device into a memory access mode when the memory is connected to the process measurement device. Also described is a power supply that ensures that the energy demand required for read access or write access to the process measurement device is automatically covered after the connection of the memory by increasing the amount of electrical energy that is freely available in the process measurement device. Undesired undersupply of the process measurement device can thereby be effectively avoided.

A radar fill level measurement device for determining a fill level of a medium is provided, including a transmitter configured to transmit a transmission signal towards the medium; a receiver configured to receive a reception signal reflected by the medium; and a controller configured to determine the fill level of the medium based on the reception signal and based on at least one evaluation parameter, the radar fill level measurement device being configured to vary a transmitting power of the transmission signal, the controller being further configured to determine a current transmitting power of the transmission signal, and the controller being further configured to vary, based on the determined current transmitting power, a value of the at least one evaluation parameter and/or at least one measurement signal that correlates with the reception signal, such that the fill level is determined taking into account the transmitting power.

Radar fill level measurement device and method for operating a radar fill level measurement device

A fill level radar device is provided, including two at least partially different signal source assemblies for heterodyne mixing of the received reflected signal of the filling material surface with a second signal in order to create an intermediate frequency signal having a uniform frequency that does not depend on the frequency of the first signal.

Fill level reflectometer having reference reflection

An antenna assembly for a level radar for detecting a topology of a filling material surface is provided. For example, the antenna assembly comprises antenna elements which are designed and/or configured to transmit and/or receive the electromagnetic measurement signal. The distances between adjacent elements are non-equidistant with respect to one another, and the minimum distance between two elements can correspond to one half of a wavelength of the electromagnetic measurement signal.

A fill level radar device for fill level measurement in accordance with the reflectometer method is provided, including a control circuit that is designed for changing the number of steps, the frequency spacings between the individual steps, the durations of the individual steps, the width of the frequency band, the frequency of the lowest step and/or the frequency of the highest step. The operating sequence can be optimised thereby.

Fill level reflectometer having a variable measurement sequence

A fill level radar device including a signal source assembly, an operating parameter determination circuit and an operating parameter adjustment circuit that is designed to change a sweep parameter of a continuous wave transmission signal on the basis of a characteristic variable of a measurement environment or measurement sequence that is input by the user or detected by the measurement device.

Fill level radar device having automated frequency adjustment

A fill level radar device including a transmission-power adjustment apparatus which is configured to adjust the power of the transmission signal depending on the frequency of the transmission signal in accordance with a predefinable correlation. As a result, frequency-dependent absorption changes in the filling material atmosphere can be compensated for by the device.

Fill level radar device having controlled transmission power

A radar level indicator comprising a processor, an analogue-digital converter circuit and an intermediate memory connected therebetween. The intermediate memory is configured to receive digital signals from the analogue-digital converter circuit at a first data rate. The processor is configured to read out the intermediate memory at a second data rate that is different from the first data rate. It is thus possible to reduce the transmission time while maintaining the same energy requirement.

Radar level indicator having a short measurement time

A FMCW fill level radar device including a control circuit for temporarily shifting, during the measuring phase, one component of the transceiver circuit into a state having reduced power consumption, resulting in the measurement being interrupted. This results in the total power consumption of the fill level radar device being reduced such that energy can be accumulated in the device, after which the measuring phase is continued.

Fill level measurement device having optimised energy consumption

A reflection microwave barrier for monitoring a limit level in at least one working area by outputting a switching signal. The reflection microwave barrier including a microwave transmitter for continuously emitting a time modulated microwave signal, a microwave receiver arranged on the same side of the at least one working area as the microwave transmitter to receive a reflection of the microwave signal, and a control circuitry communicating with the microwave receiver for a detection and monitoring of echo signals in the received reflection of the microwave signal. The control circuitry calculates the runtime of an echo signal), when the amplitude of the echo signal rises or increases. Furthermore, the control circuitry determines by the calculated runtime, whether an origin of the echo signal lies within the at least one working area, and only outputs the switching signal in this case.
