In-place inclinometers (IPI)

In-place inclinometer (IPI) sensors are designed for automatic monitoring of critical locations. Jointed together and suspended inside the casing where deformation may occur, a string of IPI sensors allows the operator to monitor the profile of the inclinometer casing on a continuous basis.

Vertical and horizontal in-place inclinometer are available in uniaxial and biaxial versions, equipped with solid-state accelerometer or force-balanced servo-accelerometer sensors.

Separated signal cables are required for each sensor. However, several in-place inclinometers can be linked together in order to create a single multi-core cable output. Horizontal in-place inclinometers are widely used in monitoring the deflection of the up-stream face of dam slopes.
