摘要： A method for initializing a communication link between a field device and a control unit according to a communication protocol is described. The communication protocol defines a broadcasting message with a data area. From the field device, a broadcasting message is generated and transmitted according to the communication protocol with a first datum in the data area. The first datum determines whether a communication connection is possible or not. The broadcasting message is received by the control unit and then, when the first datum determines the possibility of the communication connection, the communication connection is initialized by the control unit.

摘要： A probe holder for a fill level measuring device operating with the radar principle has a holder housing, a signal conductor for guiding emitted and/or received signals and a spacer. The signal conductor is led out of the interior space of the holder housing through an opening of the holder housing into a process side exterior space of the holder housing. The spacer is arranged in the opening of the holder housing and keeps the signal conductor spaced from the holder housing in the opening. The probe holder realizes a seal relative to the process area in a simple, but effective manner in that the spacer is held in the holder housing by a shrink-fit so that a sealed closure is created between the holder housing and the spacer in the shrunken-in state.

摘要： A level meter and a method for monitoring the level meter operating according to the radar principle, in which a signal conductor is lead out of an inner space of a leakage chamber of a bracket housing through a process-side opening of the leakage chamber and/or of the bracket housing into the process-side outer space of the bracket housing. The method involves transmitting a signal in the form of a pulse along the signal conductor, receiving a reflected received signal, relaying the received signal to the control and evaluation unit. In addition to the simple verification of the presence of a leak, a change in the received signal can also be quantified by the frequency spectrum of the received signal being determined and monitoring of the level meter carried out in the frequency domain.
