ABSTRACT:
The invention relates to a device for determining and/or monitoring a process variable. The aim of the invention is to provide a cost-effective, user-friendly device for determining and/or monitoring a process variable. The inventive device comprises the following elements: a sensor, a measuring/regulating/control unit which pre-defines at least one event to be determined or monitored, and at least one memory unit which stores data according to the at least one pre-defined event. The sensor, the measuring/regulating/control unit and the memory unit form a compact unit or an independent field appliance.
