摘要:
An electronic scale having a measuring sensor (1 . . . 16), a digital signal processing unit (18), a digital display (19) and an inclinometer (40). The inclinometer derives a signal for the tilt of the scale from the difference of at least two signals. The digital signal processing unit (18) is provided with an additional circuit component or program routine that adds the two signals and, by way of this cumulative signal, corrects the vibration-distorted signal of the measuring sensor (1 . . . 16). A plurality of inclinometers enables the simultaneous detection of momentary gravitational acceleration. For example, in an electric bubble level, the gas bubble moves out of place when tilted and the diameter of the gas bubble changes when the gravitational acceleration changes. The scale thus provides an additional signal for correcting the influence of disturbances with minimum complexity.
