In-place inclinometers (IPIs) make use of tilt sensors to take accurate measurements of lateral movement in embankments, landfills, piles, piers, retaining walls and abutments. The sensors are attached with cabling and installed in inclinometer casing. This casing provides access for sub-surface measurements and grooves control the orientation of the sensors. When the ground or structure moves, the casing moves with it, changing the inclination of the sensors inside it. A summation of the tilts from the sensors are processed to provide graphs of the casing profile and changes in that profile. These changes indicate displacement, or movement. In-place inclinometers are typically used for safety critical applications where near real-time monitoring and early detection is critical. Today's inclinometers make use of MEMS technology making installation simple and easy.
