Abstract:
1. A method for the temperature correction of a force-measuring device operating in measurement mode, comprising: generating, by means of a force-measuring cell, an electrical force measurement signal corresponding to the input force; measuring a temperature by means of a temperature sensor that is arranged at a distance from the heat-generating components of the force-measuring device, wherein said temperature corresponds primarily to an ambient temperature to which the force-measuring device is exposed, and generating a temperature measurement signal corresponding to the measured temperature; processing the force measurement signal and the temperature measurement signal to obtain a temperature-corrected output signal; and transmitting the output signal to an indicator unit and/or to a further processing unit, wherein processing the force measurement signal and the temperature measurement signal includes calculating at least one correction parameter serving for the correction of the output signal from the force measurement signal and the temperature measurement signal based on a thermodynamic model wherein said correction parameter represents a temperature difference which exists between at least one of a) a system temperature and the measured temperature, and b) a first system temperature and a second system temperature.
