EL3356 | 1-channel accurate resistance bridge evaluation

The EL3356 analog input terminal permits direct connection of a resistance bridge. The ratio between the bridge voltage UD and the supply voltage UREF is determined in the input circuit. In order to achieve good long-term stability, the complete circuit is re-calibrated at least every 3 minutes. This procedure can be synchronised by the control in order to prevent the calibration leading to a delay in the production process.
