Analogue=digital converter for process automisation - provides successive values for discrete time intervals within given integration time

摘要

The analogue/digital converter converts the input analogue signal (U) into a corresponding digital measured value during a given integration time (T). The latter is divided into successive time intervals (dT), with a respective value provided for each of these intervals. The actual digital measured value (Mi) at a selected point during the integration time (T) is provided by digital filtering of the values provided up to this point. The actual digital measured value (Mi) is pref. obtained from the mean value of the values provided during the integration time. ADVANTAGE - Provides digital values quickly, while suppressing noise.
