In-Place Inclinometer

Inclined In-place Inclinometers (IPI) are used primarily for monitoring the downstream concrete face of rock filled dams or other inclined applications.

They are installed within inclinometer casing, which is either placed in a borehole, concreted in or attached to a structure. They consist of a series of wheeled sensors placed at various depths within the casing which are connected together with extension rods. Each sensor has specially designed connectors which allow them to move independently.

They consist of a series of wheeled inclinometer probes which contain one or two MEMS sensors and are placed at various depths within the casing and connected together with extension rods. The electrical BUS connection between each sensor is routed internally through the extension rod ensuring water-tightness and eliminating external connectors which are prone to leak and damage. This unique cable-free joint design ensures quick and easy watertight connection.

The design allows each sensor to move independently to each other without influence from the sensors above or below. This provides a profile of displacement over the complete length of the installation. The extension rod lengths can be varied to suit individual gauge length requirements and sensors can also be concentrated in areas where movement is expected.

In-place Inclinometers are typically used and designed for safety critical applications where ‘real time’ monitoring and early warning is required in order to protect life and valuable assets. They are easy to automate using data acquisition systems, WI-SOS 480 wireless communication and the data can be visualised using the GeoAxiom Vista software.

There are three different kinds of in-place inclinometer:

  • Inclined
  • Vertical
  • Horizontal
