To provide a device for vibration compensation in a weighing sensor weight signal.
The device includes a weighing signal branch line including an analog-to-digital conversion unit 5, an analog weighing signal of a weighing sensor 3 is sent to the unit, a digital weighing signal including a separated detection value of the analog weighing signal is generated, and the device includes at least one compensation signal branch line. The branch line has an analog-to-digital conversion unit 11, and can send, to the unit 13, an analog noise amount signal of an acceleration sensor 19 for detecting an acceleration noise amount of a defined direct acting direction or about a defined rotation axis. The unit generates a digital weighing signal including a separated detection value of a detected analog weighing amount signal of the acceleration sensor. The branch line has a digital filter unit 15, and an addition unit 7 for adding the signal value of the digital weighing signal and the signal value obtained by adding a minus sign to the digital weighing amount signal.
