Applications


Infrastructure tilting condition monitoring of accuracy 0.01°, such as retaining wall, supporting column, river embankment etc.
From the 1st level of data conversion, the movement of one end of a beam/crossbar can be monitored (with accuracy of 0.17mm/m), such as land sliding, railway track monitoring.
With our latest developed mathematical model, we can achieve a 0.3mm accuracy for the Horizontal Convergence of a metro tunnel of 6 segments in Shanghai Metro.
