摘要： A fill level measuring device working with microwaves according to the travel time principle for fill level measurement of fill substances located in containers. On a plurality of different signal paths, microwave signals can be transmitted into the container, and their associated echo signals recorded. The measurement results gained on the different signal paths can be evaluated separately from one another. The device includes: measuring device electronics having a microwave generator for the successive production of microwave signals having different wanted frequencies; and, connected thereto, a frequency-selective, passive antenna arrangement, which has a plurality of antennas, which serve to transmit successively the different microwave signals into the container, and to receive their echo signals reflected back to the antenna arrangement, and which has a number of frequency-selective elements—especially bandpass filters—in each case transmissive for one of the different wanted frequencies. Via the antennas and the frequency-selective elements, for each of the different microwave signals and its echo signal, a uniquely associated signal path is specified, via which a microwave signal is transmitted into the container and its echo signal, reflected back to the antenna arrangement (SM, SN, SL), is received and fed to the measuring device electronics. The device also includes an apparatus, which is provided in the measuring device electronics and which associates successively arriving echo signals with the associated signal path.

摘要： A method for ascertaining and monitoring fill level of a medium in a container by means of a field device with a travel time measuring method, wherein, in a learning phase, application- and device referenced test signals and response signals expected from a fill level upper surface are determined and, therefrom, application- and device referenced comparison signals are ascertained, wherein, in an operational phase, test signals are transmitted toward the medium and application- and device referenced, response signals are received, as well as, by means of a comparison algorithm, the comparison signals are compared with the response signals and a value for an agreement probability is ascertained, and wherein, upon exceeding the ascertained value of the agreement probability above a predetermined limit value, the fill level is ascertained and outputted as a measured value and/or, in the case of subceeding, or falling beneath, the predetermined limit value, a new test signal is transmitted for renewed ascertaining of a response signal.

摘要： In order systematically to register individual, or a combination of, adverse influences on, and in order to be able better to estimate, service life or ability of a measuring field-device to function, at least one relevant influencing variable, preferably, however, a plurality thereof, is/are evaluated. In such case, Oin addition to a measured value [[(24)]] for a process variable, further variables [[(25) and (26)]] are registered by corresponding sensors mounted on, or in, the measuring field-device and conditioned in analog format in suitable operating circuits, preparatory to registering them digitally with the same A/D-converter [[(21)]] that registers the measurement signal [[A]] for the process variable. Multiplexer [[(22)]] permits selection of the desired input signal, which is then processed further with the aid of a microprocessor [[(23)]]. Then, the combined effect of the different influencing variables is determined and a remaining, probable service life calculated. In case the influencing variables [[(25, 26)]] assume critical values, the microprocessor [[(23)]] can trigger an alarm signal.
