Interfels In Place Inclinometer (IPI) is designed for near vertical borehole applications, the principal operation and data obtained are similar to the traversing type inclinometer systems such as the portable Digital Bluetooth Inclinometer systems. Typical applications of the IPI system include the monitoring of landslide areas, stability of natural slopes and Dams, railroads, highways, landslide areas and early warning of a pending slope failure, ground movements due to tunnel construction and excavation as well as monitoring deformations of embankments and retaining walls.

The In Place Inclinometer system utilises a fixed string of inclinometer probes separated by rigid gauge tubing, the main advantages include rapid automatic data logging and real-time monitoring. The IPI sensor incorporates a MEMS accelerometer making the instrument virtually shock proof, giving a high degree of repeatability and accuracy. The sensor incorporates an on-board microprocessor which performs an automatic temperature compensation of the tilt (g) data. The sensor is a very low power, low EMC device which conforms to the specifications laid down under EN50121 1-4, making it particularly suitable for work on or adjacent to railway lines and in tunnels.
