Abstract: A device for measuring force and for monitoring wear on overhead lines includes a force-measuring system which includes two contact bars which, in an operating state, are oriented at a right angle to an overhead line to be monitored, and two connection bars, which, in the operating state, are oriented parallel to the overhead line. A bar-shaped force transducer is fastened to each end portion of the two connection bars and each of the bar-shaped force transducers extends in an axial direction of the respective connection bar.

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.

Abstract: A device for measuring physical values, each as pressure changes, includes a sensor transponder section and an interrogator receiver section for transmitting interrogation signals including a power supply from the interrogator receiver section to the sensor transponder section and for transmitting measured signal values in the opposite direction. The sections can be coupled to each other by inductive coils so that electrical connections are avoided. Thus, the pressure in a rotating automobile tire can be measured, for example. The sensor transponder section includes a computer circuit the input of which receives a reference frequency signal and a measured frequency signal. A reference oscillating signal has a frequency determining element that is not influenced by the pressure to be measured, but only by extraneous, e.g. environmental influences. A measuring oscillating circuit has a frequency determining element that is responsive to the changes in the physical value to be measured.
