A printed circuit board for a radar level measurement device with a printed circuit board substrate is provided, wherein a microwave signal is coupled via a microwave conductor into a waveguide. A connection region on a front side of the printed circuit board substrate serves to receive the waveguide. A shape of a resonator shell is generated inversely by producing an annular peripheral recess whose wall has an electromagnetically reflecting coating on a rear side of the printed circuit board substrate. The annular peripheral recess on the rear side, together with a region surrounded by the recess, forms a resonator for the injected microwave signals.

A measurement device is provided for determining a distance of the measurement device from a medium and a flow speed of a medium by evaluating a transmission signal emitted by the fill level measurement device and reflected by the medium. The measurement device includes an antenna arrangement for emitting the transmission signal in two different directions. The flow speed of the medium can be determined using the Doppler shift of the transmission signal.

Determining a level and flow speed of a medium

A fill level measurement device is specified for determining distance of the measurement device and flow speed of a medium, which comprises a frequency-modulated transmission signal having a rising and a falling frequency ramp. The flow speed of the medium can be determined by the Doppler effect arising from the flow speed of the medium.

A sensor includes an electronic module that comprises several electronic subassemblies and a processor that can be electrically coupled to the electronic subassemblies. The subassemblies respectively feature a programmable storage device with subassembly-specific data of the respective subassembly. The content of the respective programmable storage devices can be read out and evaluated by the processor.

Stated is a process separation device for a fill-level measuring device including a pressure resistant feed-through for an inner conductor. The process separation device comprises an inner conductor, an outer conductor, a process side, a control side, and a feed-through. The inner conductor comprises a first conical region, and/or the outer conductor comprises a second conical region. The feed-through comprises the first conical region and/or is encompassed by the second conical region, and in this manner establishes a connection having positive fit between the inner conductor and the outer conductor.

A field device for measuring a filling level, a pressure or a density of a medium in a container includes data memory with two memory areas that are separated from one another. First data for safety-critical program modules is stored in the first memory area. Second data for safety-uncritical program modules is stored in the second memory area. The two memory areas are separated from one another. All access to these memory areas is controlled by a memory management unit.

Field device with separated memory areas

An electronic module for level measurements, pressure measurements or density measurements is disclosed. In the module, a safety-relevant function is transferred into an area that is categorized as safety-uncritical. In order to prevent malfunctions, a diagnostic function is performed in the safety-critical area of the electronic module in order to check the transferred function. This diagnostic function is also checked with respect to its effectiveness during the safety-oriented operation. Suitable measures can be initiated in case an error is detected.

A conductor leadthrough for a field device is for connecting two electrical conductors. The conductor leadthrough comprises an external conductor and a sealing apparatus. The sealing apparatus is divided into a first separation device and a second separation device. The external conductor comprises a hollow internal region that extends along a longitudinal axis of the external conductor. The first separation device and the second separation device are arranged along the longitudinal axis of the external conductor so as to be spaced apart so that they can separate a section of the hollow internal region of the external conductor. A pourable-sealing device is filled into the separated section of the hollow internal region of the external conductor so that the sealing apparatus can provide a leakage rate whose value is below a predeterminable value of a leakage rate. A signal of a predeterminable frequency can be transmitted along the longitudinal axis.

A metalized plastic antenna includes a plastic antenna body with metallization on the inside. In this arrangement metallization is used for conducting electromagnetic waves. Furthermore, metallization may be implemented as a protective coating so that chemical resistance of the plastic antenna may be ensured even in the case of corrosive environmental conditions.
