Tiltmeters and Inclinometers

Analogue Tiltmeter

Description

Our analogue tiltmeter allows measurement of the variation in tilt of a rigid body in two orthogonal directions. A tiltmeter is a sensitive inclinometer designed to measure very small vertical level changes in geotechnical monitoring systems or in structural monitoring systems. Tiltmeters are used mainly for monitoring the response of concrete or CCM dams to filling, the small movements of potential landslides and hydraulic fractures, and the response of large structures and buildings to various influences. Tiltmeters may be mechanical or incorporate vibrating-wire or electrolytic sensors in electronic instruments.

The instrument is fixed in-place and when connected to an automatic acquisition system allows long-term observation as scheduled.

The instrument is available in mono and biaxial version; in an IP66 housing for positioning horizontally or on a vertical wall.
Versions for outdoor use or for submersion at high pressure are available – IP68 up to 300m of water column.

Applications

The Analogue Tiltmeter, in its standard versions, is used for measuring the tilt variations of structures.
Depending on the mode of installation, the instrument can be used for the detection of deformations or movements of both rigid and incoherent.”bodies,”
Used especially in the railway field for the monitoring of tracks, it also finds application in structural monitoring during both constrution phases and subsequent management of the works. Also generally used for:

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

Features and Benefits

  • Available in mono or biaxial form
  • Use 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 analogue tiltmeter 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 where monitoring of structural deformation is required, in addition to monitoring variations in inclination and tilt.

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 applicationsUsually, systems with multiple sensors are produced, either separate from each other or interconnected with extension bars which allow the formation of chains for the monitoring of subsidence and structural deformation. The instrument chain allows the monitoring of an entire profile (as opposed to single points), thus providing a greater accuracy of measurement.

These sensors with 4-20mA exit, allow easy interfacing with our Data Logger CUM3000 and various other reading and acquisition systems currently available on the national and international market.
