Electrolevel Beam Sensor

Electrolevel Beam Sensors detect differential movement and rotation in structures. Two versions of the beam sensor are available: horizontal for monitoring settlement or heave and vertical for monitoring lateral displacement and convergence.
Since the EL beam sensor has a defined gauge length, changes in tilt can be converted simply and accurately to millimetres of movement, regardless of the rigidity of the structure. Linked end to end, beam sensors can provide absolute displacement and settlement profiles.

Typical applications include:

  • Monitoring stabilisation measures, such as pressure grouting and underpinning
  • Monitoring structures for the effects of tunnelling 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

  • Low profile design makes the EL beam sensor practical to install in tunnels and other locations where clearance is important
  • The length of the beam can be modified to fit the structure, and special mounting brackets provide easy installation on curved or distorted surfaces
  • The electrolytic tilt sensor has no moving parts
  • Can be read manually at a remote terminal box with a handheld electrolevel meter (HELM)
  • Provides reliable, high-resolution measurements, is simple to install, and is easily connected to a data acquisition system
  • An efficient and economical alternative to precision levelling surveys and settlement profiling systems
