摘要
In a measuring arrangement comprising a strain gage section (10) constructed of at least one SG (strain gage) (15), and integrated in a measurement pickup (1), an additional circuit (20) amplifies modulated output signals of the SG section (10), and is also integrated in the measurement pickup (1). The measuring arrangement thus obtained is used for general measuring tasks, particularly for commercially available domestic or industrial scales including weighing devices operated by means of commercially available batteries. As an additional circuit, a modulation amplifier can be used which consists of a modulator constructed as squarewave generator, an alternating-voltage amplifier and a demodulator, the demodulator being a bridge rectifier composed of four electronic (on/off) switches or two electrical changeover switches.
