摘要:
An exemplary method for the temperature correction of a force-measuring device such as a balance is disclosed. The method includes generating, by means of a force-measuring cell, a force measurement signal corresponding to the input force; generating an electrical temperature measurement signal by means of a temperature sensor that is arranged at a distance from the heat-generating components of the force-measuring device, processing the force measurement signal into a temperature-corrected output signal based on the temperature measurement signal and the force measurement signal; and transmitting the output signal to an indicator unit and/or to a further processing unit.
