Abstract
The output signal from a measuring transducer in a force-measuring device is processed by filtering a measuring signal (ms), representing a load that is acting on the transducer, to suppress interfering signal portions caused by extraneous influences including mechanical disturbances, or changes of the load. The measuring signal (ms) passes through a first delay element (A) to a measurement value unit () which holds the value of the currently received measuring signal (ms), a mean value based on the most recent values of the measuring signal, or an expected value (ms) based on the most recent values of the measuring signal. The measuring signal (ms) is monitored for signal disturbances using a first detector module (). After detection, a switching means () is actuated and the output signal (ms) of the measurement value unit is processed further, if applicable, and sent to the output end of the device, instead of the currently received measuring signal (ms).
