METHOD FOR MONITORING A POWER MEASUREMENT DEVICE, A POWER MEASURING DEVICE AND A POWER MEASUREMENT MODULE

摘要

1. A method for monitoring the state of a force measuring device (1, 200), in particular a weighing device, with a movable force transmitting element (40, 240) through which the force acting on the force measuring device (1, 200) is transmitted to the measuring transducer (14, 214) that generates a measurement signal (SF) corresponding to the applied force, after which the signal is converted into a form suitable for displaying or transmitted for further processing, characterized in that at least one parameter is determined (M ), which characterizes freedom one mobility of the force transmitting element (40, 240) or a change in the aforementioned free mobility in time, the parameter (M) being compared with at least one threshold value (T) and, depending on the comparison result, either a normal state or a limitation is detected the free mobility of the force transmitting element (40, 240), and moreover, in the case where a restriction on free mobility has been detected, the force measuring device (1, 200) is activated. ! 2. The method according to claim 1, characterized in that the quantity characterized by the parameter (M) is mainly translational velocity and / or angular velocity and / or translational acceleration and / or angular acceleration and / or kinetic energy, in particular , specific energy of angular displacement (Eθ) of the force transmission element (40, 240). ! 3. The method according to claim 1, characterized in that the quantity characterized by the parameter (M) is mobility in at least one direction, which is oriented substantially orthogonally to the direction of the force path to the transmission element (40, 240) strength. ! 4. The method of claim 1, characterized in that
