Abstract:
1. A method for processing an output signal of a measurement transducer incorporated in a force-measuring device, comprising the steps of: producing, in the measurement transducer, a measuring signal representing a load acting on the transducer; filtering the measuring signal to suppress interfering signal portions caused by extraneous influences; directing the filtered measuring signal to a first delay element that imposes a time delay thereon, resulting in a delayed, but otherwise undisturbed, filtered measuring signal that is delivered to a switching means, where the imposed time delay exceeds the time required to switch a changeover switch of the switching means; directing the filtered measuring signal to a measurement value unit, which delivers an output signal at an output thereof, the output signal selected from one of: monitoring the measuring signal in a first detector module incorporated in a controller unit to detect signal disturbances, and actuating the switching means when a signal disturbance is detected, to interrupt the delivery of the filtered measuring signal to the measurement value unit and to send the output signal of the measurement value unit to the downstream-connected modules of the force-measuring device, instead of the delayed measuring signal.
