  • Patent number: 10330516
    Abstract: 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.

  • Publication number: 20170328762
    Abstract: 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.

  • Patent number: 9377330
    Abstract: A method for monitoring a transmitter that has a measurement unit and a transmission unit which are interconnected to each other in order to transmit signals. There is at least one connecting line for supplying power to the measurement unit which determines a measurement quantity and generates a measurement signal which is dependent on it. The transmission unit receives the measurement signal from the measurement unit, and based on the measurement signal, transfers an output signal to at least one signal transmission element. To provide a method for monitoring a transmitter which allows reliable displaying of an error as easily as possible and the shifting of the transmitter into a secured state, in the case in which the measurement unit detects the presence of an error state, the measurement unit acts on the connecting line.

  • Patent number: 8902553
    Abstract: A measuring arrangement for determining at least one measured quantity with a sensor device and a transmitter device that has a control device, a switch device and a signal output setting device. The control device is connected to the signal output setting device in the case in which the switch device is in the first state.

The sensor device keeps the switch device in the first state when the sensor device is supplied with energy above a definable minimum value. The control device reduces the power supply of the sensor device to a definable boundary value when it recognizes the presence of a fault state.

  • Patent number: 7730780
    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.
