Abstract: The present disclosure relates to a method for predicting a measured value of a measured variable of a sensor of process automation technology, includes the steps of capturing a first measured value at a first point in time; capturing a second measured value at a second, later point in time, formation of a differential value between the second and first measured values, filtering out the differential value using a filter with an infinite impulse response, and calculating a future measured value using the measured value at the second point in time, the filtered differential value, and a constant that characterizes the sensor. The present disclosure further relates to a conductivity sensor including a temperature sensor and a computer unit for executing a method.

Abstract: A method for operating a measuring point for determining at least one measured variable of a medium is disclosed. The measuring point includes a base unit, which is connected releasably with a sensor unit, and which is provided for communication of a signal representing the value of the measured variable to a process monitoring facility. The following steps are included: at least one-time registering and storing in the base unit a value of a diagnostic parameter stored in the sensor unit or produced by the sensor unit; on the basis of this value conforming a prognosis value or prognosis interval stored in the base unit, and storing the conformed prognosis value or prognosis interval in the base unit in place of the previously stored prognosis value or prognosis interval.
