MEMS Tiltsensor

MEMS Tiltsensor Overview

The MEMS Tiltsensor is based on the Geomotion In-Place Inclinometer (IPI) sensor and is designed for attaching to structures where a large tilt range is required.

Mounted within the Stainless Steel housing are one or two (uniaxial or biaxial) MEMS sensors that deliver a large measuring range with high sensitivity and relative immunity from the effects of long cable lengths.

The MEMS Tiltsensor is a small discrete device which measures in g (gravity), providing reliable, accurate and stable data.

Each sensor incorporates an on-board microprocessor which performs an automatic temperature compensation of the tilt (g) data.

The sensors are powered and the readings obtained by a datalogger. The data can be directly imported into ‘ARGUS’ monitoring software, providing a near real time profile of displacement that is constantly updated.

Product Features

  • Accurate and precise measurements using MEMS sensors
  • Available in uniaxial and biaxial versions
  • Inbuilt temperature compensation
  • Stainless Steel construction, waterproof to 2000kPa

Product Benefits

  • Easy to automate using data acquisition systems and ‘Argus’ software
  • Removes the need for manual monitoring
  • Suitable for safety critical applications
  • Low power consumption

Operation

Once the location for the MEMS Tiltsensor has been established the position is marked out, ensuring that the sensor is correctly orientated towards the direction of movement.

The marked locations are drilled to depth and the 8mm shell anchors supplied with the Tiltsensor are installed. Studding is screwed into the shell anchors, leaving a sufficient length to incorporate the bracket and the Tiltsensor.

Once the studding is in place, the Tiltsensor bracket is mounted on to the studding, ensuring there is an adequate space between the structure and the Tiltsensor before securing in place using the M8 washers and nuts.

A spirit level is used to check that the Tiltsensor is level in both directions, and then the nuts are securely tightened before the Tiltsensor is finally wired into a datalogger.

The system can be fully automated using ‘ARGUS’ monitoring software, providing a near real time profile of displacement.

Application

The MEMS Tiltsensor monitors vertical rotations of structures. Its most common use is to monitor settlement and heave of existing structures and tunnels caused by adjacent excavations or tunnelling works.

The sensor is especially useful where topographic measurements are precluded or where access is restricted.

Typical monitoring applications include:
  • Brick and stone buildings
  • Vertical rotation (heave and settlement) due to adjacent construction activities
  • Bridges and dams
  • Impounding and loading effects in short or long term
  • Differential levels
  • Tunnels
  • Monitoring vertical rotation and track formation

Technical Rating

As the correct installation of any monitoring sensor or system is vital to maximise performance and accuracy, Geomotion makes the following recommendations for the skill level of the installation contractor.

Technical Rating for this Product:  ADVANCED

The installer is trained and experienced in the installation of this type of instrument or systems, and is ideally a specialist Instrumentation and Monitoring contractor.
