Description

Our MEMS Tilt Beam allows measurement of the variation of inclination of a rigid body in two directions orthogonal to each other.

The instrument is fixed in-place, allowing when connected to an automatic acquisition system, the scheduling of long-term periodic observation

Digital output enables the formation of clinometer chains made from “n” sensors with just one serial cable connected to the acquisition unit.

The instrument is available in mono and biaxial versions, with IP66 housing for placement on a plane or on a vertical wall.

Two versions are available: for outdoor use or for immersion to great pressure (IP68, up to 300m of water column).

 

 

Applications

The instrument, in its standard versions, is used for monitoring tilt changes in structures.

Depending on installation mode, the instrument can be used for the detection of deformation or movement of bodies.

Particularly used in the rail engineering for the monitoring of tracks, it also finds application in structural monitoring both during the execution and management of works.

Also used with:

  • Support walls
  • Bridges
  • Dams
  • Landslides
  • Embankments
  • Monuments
  • Structures of archaeological interest
  • Towers
  • Chimneys
  • Minarets
  • Various

Features and benefits

Available in mono or biaxial form:

  • Installation on vertical or horizontal surfaces
  • Digital output
  • Digital bus
  • Manual or automatic readings
  • High accuracy and repeatability
  • Easy to install
  • Robust and compact
  • Ideal for all applications
  • IP67; IP68 on request

 

Measurement principle

The clinometer is composed of two single-axis MEMS sensors (Micro-Electro-Mechanical-System) The sensitivity, reliability and robustness of the sensor, make this instrument a great low cost aid for monitoring systems which measure structural deformation in addition to rotation and variations in tilt in general.

Installation is simple and immediate, fixed to the wall with 3 Fischer fixings and a simple initial check with an optical level

Adjustment and refinement plates are available for special applications.

Usually, systems with multiple sensors are produced, with sensors either separate from each other or interconnected with extension bars to allow the formation of chains for the monitoring of subsidence and structural deformation. The instrument chain allows the monitoring of an entire profile (rather than single points) and provides greater accuracy in overall measurement.

These sensors with RS485 (MODBUS) exit, allow easy interfacing with our Data Logger CUM3000 and other reading and acquisition systems available on national and international markets.
