MEMS In place Inclinometer (IPI)

The In Place Inclinometers (IPI) we offer are composed of an integrated system, where power supply electronics, transmission signal electronics and MEMS (Micro Electro-Mechanical System) sensors, are housed together in one probe casing. The instrument is fully waterproof and is suitable for use in conventional inclinometer columns. It is normally used with an inclinometer tube in drilled holes for the monitoring of horizontal movement in soil, landslides and deformations of structure.

Generally this type of sensor is used to form chains inserted into the same tube, thereby providing automatic measurement of the deformation of an inclinometer column (as an alternative to systems with manual probe inclinometer).

Applications

The IPI system is used to monitor movements in soil or movement of structures. Usually the In-Place Inclinometer (IPI) is used to measure lateral displacement within a borehole. Commonly, the IPI is used in a system where multiple IPIs are installed at varying depths to monitor the response of concrete or CCM dams to filling, the movements of potential landslides and hydraulic fractures, and the response of large structures and buildings to various influences.

In place inclinometer tubes can be used for many applications:

Landslides
Identification of shear zones
Diaphragms
Piles
Dams
Tunnels
Bridges
Road and railway embankments
Various

Features and Benefits
