Wen Li · Journal of Tianjin Normal University · 2001
A special instrument for measuring strains of railway bridge beam on dead or moving load by using micro-controller 8031 as intelligent device and strain guage as sensor has been developed .Automatic bridge balance adjustment and programmable gain amplification as well as zero drift correction technique have been employed to ensure sufficient high accuracy and reliability for the measurement results. The Instrument has advantages of high memory capacity,site display,printing,multiplepoint data recording and replay functions.
