Abstract
The present invention relates to a measured value transducer (3) having an internal data memory (32), a processing apparatus (2) for such a measured value transducer (3), and a method for storing data in an internal data memory (32) of such a measured value transducer (3). The internal data memory (32) comprises a plurality of memory areas. A respective count value, which corresponds to a frequency of an occurrence of measured values in a certain measured value range, is respectively stored in at least two memory areas of the plurality of memory areas. Thereby, data relating to a loading of a measured value transducer can be stored directly in it and can later be directly and unambiguously allocated to it. Thereby a tamper-proof storage of the data is possible, and a producer or seller of the measured value transducer can determine whether it has been overloaded, in case that e.g. a complaint is made by an end user. In addition, conclusions about the measuring accuracy and/or the service life still to be expected of the measured value transducer are possible.
