The IPI-X is designed to be installed in inclinometer casing to automatically measure settlement or heave, together with tilt for full 3D borehole profiling.
The IPI-X is an Automatic Magnetic Extensometer combined with an In-Place Inclinometer which can be used typically to measure vertical and horizontal displacement in embankments, dam foundations, deep foundations and around tunnels and diaphragm walls.
It comprises an In-place Inclinometer with the addition of a low power digital Magnetic Positional Sensor inside the adjoining extension rod, placed in conventional inclinometer casing.
Magnetic targets are positioned along the length of the inclinometer casing next to the location of the Magnetic Positional Sensors. Horizontal displacement is measured through tilt by the In-Place Inclinometer to provide a 3D profile of the borehole. All the digital sensors are bussed together allowing fast and reliable communication.
Any combination of extension rods (1, 1.5, 2 & 2.5m) and IPI sensors (0.5m) allow placement at the desired depths.
To provide an absolute reference for vertical displacement, the bottom magnetic target should be installed into stable ground together with a geodetic survey of the top of the installation.
The RS-485 BUS is compatable with wireless interfaces and conventional data loggers that support serial interfaces.
