    摘要: A measuring device for process automation in an industrial or private environment is provided, including: a sensor circuit configured to detect one or more measured variables; and a control circuit configured to determine a measurement result from the detected one or more measured variables and to determine a difference between a temperature of the sensor circuit and a reference temperature detected during a calibration of a self-test function of the measuring device, the control circuit being further configured to perform a correction of the measurement result depending on the difference between the temperature of the sensor circuit and the reference temperature during execution of the self-test function. A method for performing a correction of a measurement result of a measuring device for process automation in an industrial or private environment is also provided.

    摘要: A radiometric measuring device for determining an intensity of pulses of an interference signal from an external radiation source, wherein the radiometric measuring device carries out fill level or limit level determination of a filling material in a container. The radiometric measuring device has a detector which is configured to receive pulses of a useful signal modulated with a modulation frequency from a gamma emitter and additionally pulses of the interference signal from the external radiation source. Further, the measuring device comprises an averager configured to output a first count rate of the pulses at an averager output, and a bandpass system comprising a bandpass with adjustable passband frequency range configured to output a second count rate of the pulses at a bandpass system output. The measuring device further comprises a subtractor adapted to form a differential count rate between the first count rate and the second count rate.

    摘要: A system for testing a process chain in an industrial environment, wherein the process chain has at least one field device, comprises a control unit and a mobile terminal device. The control unit communicates with and controls the at least one field device during a testing process and/or read out of data. The mobile terminal device has at least one recording device configured for recording a behavior of at least a part of the process chain, and the mobile terminal device is configured for generating, from information recorded by the at least one recording device, a log record of the at least one part of the process chain and storing the log record.
