| Abstract: | A new multichannel strain measuring system has been designed. The system can eliminate the effects from the drifts of operational amplifier, A/D convertor and active bridge during measurement, and has extremely high accuracy and stability. The principle not only can be used in strain measurement but also in temperature and pressure measuring systems. The character astics of system, correction factors and experiment conclusion are analyzed. |
