A measuring element of a local sensor provides elementary measuring units, which correspond to at least one physical or physico-chemical variable or at least one physical or physico-chemical parameter, as raw measurement data. In order to determine the measurement resolution of the sensor, the conditions for generating time stamps are determined in advance using a correlation model, time stamps of successive raw measurement data are generated in the sensor on the basis of the correlation model, and the time stamps are transmitted via a wired connection and/or via a radio path. The raw measurement data are reconstructed and evaluated based on the time stamps with the correlation model. The conditions for generating time stamps can be changed dynamically within the framework of the correlation model.
