Abstract:
1. A method for operating a measuring point for determining at least one measured variable of a medium, wherein the measuring point comprises a base unit, which is connected releasably with a first sensor unit, and which is provided for communication of a signal representing a value of the measured variable to a process monitoring facility, the method comprises steps of: a) at least one-time registering and storing, in the base unit, a value of a diagnostic parameter stored in the first sensor unit or produced by the first sensor unit; b) on the basis of said value of the diagnostic parameter stored in the base unit, conforming a prognosis value or prognosis interval stored in the base unit, said prognosis value being a prognosis value of said diagnostic parameter and said prognosis interval is a confidence interval surrounding the prognosis value; and c) storing the conformed prognosis value or prognosis interval in the base unit in place of a previously stored prognosis value or prognosis interval, wherein: the conforming of the prognosis value or prognosis interval occurring by means of a learning algorithm, which is embodied to learn, over the lifetime of a plurality of sensor units, said prognosis value or prognosis interval: said diagnostic parameter is a total loading reserve, a total operating time, operating times under defined conditions or a counter state; and said prognosis interval is a confidence interval surrounding the prognosis value; wherein a counter state is one of: a counter state for counting cleaning in process (CIP) steps, a counter state for counting sterilization in process (SIP) steps or a counter state for counting autoclaving steps.
