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. |
Tilting Orientation |
Tilting Mark | |
As shown below, readings (of the blue axe) get smaller from Status 1 to Status 2; increase from Status 1 to Status 0. |
Installation Guidance: Ensuring the tilt node is installed parallel to the horizontal ground plane. |
