Description
Summary:In this paper, a simplified technique is proposed which enables the user to nullify offset whenever power is switched on of the circuit and also based on the requirement of the user. In this method strain sensor is the part of the resistive bridge which is used as Quarter Bridge. The voltage excitation to the bridge is provided by a voltage reference. The output of the bridge reaches precision sensor signal amplifier through over-voltage protection circuit. Dynamic range and bridge offset adjustment both can be achieved in the circuit as per requirement. High precision Analog to Digital Converter digitizes data. The output is then captured on the monitoring computer to verify the results.
