A method for accurately acquiring multiple analog input signals that are converted using a plurality of A/D converters into corresponding digital single measured values. A first measurement averaging cycle having a predetermined total number of measuring intervals is predetermined by a higher-order control unit. First and second input signals are acquired by first and second A/D converters in a first and second number of measuring intervals, the second number being smaller than the first number. The first and second input signals are averaged to form first and second measured values, respectively. The first input signal is acquired by the second A/D converter in a third number of measuring intervals as at least one further single measured value. A message is output if a deviation of the at least one further single measured value from a single measured value of the first input signals measured by the first A/D converter or from the first measured values averaged up to that point exceeds a maximum permissible absolute value of the deviation.

Method for accurately acquiring multiple analog input signals, analog input circuit, and measuring sensor and measuring transducer having an analog input circuit of this type

A measuring transducer with a sensor for converting a detected measured value into a sensor signal. The sensor signal is processed in a signal processing device to form a measuring signal that is transmitted to a central location via a data interface. The data interface is also used as a conduit for signals to parameterize the measuring transducer. The measuring transducer includes a device that provides a simulated measuring signal that can be transmitted to the central location on request via the data interface instead of the detected measured value. Further, a function can be performed on the simulated measuring signal before it is transmitted or a sequence of simulated measuring values can be transmitted corresponding to particular operating conditions.
