Electro Level Beam (ELB)

 
  

el beam sensor

EL beam sensors are used to monitor differential movement and rotation in structures. Typical applications include:

  • Monitoring stabilization measures, such as pressure grouting and underpinning.
  • Monitoring structures which may be affected by nearby tunneling and excavating.
  • Evaluating the performance of bridges and beams under load.
  • Monitoring the stability of structures in landslide areas.
  • Monitoring the deflection and deformation of retaining walls.
  • Monitoring convergence and other movements in tunnels
