Abstract
The invention relates to an arrangement for processing the output signals of a resistance bridge supplied with a DC voltage or a direct current with periodically reversed polarity. The arrangement further comprises a clock generator furnishing a clock signal controlling said reversal. The output signal of the resistance bridge is amplified in a bridge amplifier and supplied to a voltage-frequency converter with signal and reference inputs. The output frequency of said voltage-frequency converter is the output signal of the arrangement. The instantaneous bridge supply is used as reference for the voltage-frequency converter and the reversal of the polarity of the bridge supply is synchronized with the output frequency. The measurement of the output frequency in the following evaluating units takes place in such a manner that the mean value is formed over a whole number of reversal clock periods.
