1 _ IN-PLACE INCLINOMETERS inclinometers & pendulums

2 IN-PLACE INCLINOMETERS S410 In-Place Inclinometer (double wheel-carriage) is specifically designed to combine the benefits of automatic monitoring and the selective installation of probes at different depths. This configuration allows a cost effective solution in those cases where the critical depths are known. Consequently the probes may be concentrated only in some areas along the borehole profile. IPI probes are equipped with self-compensated MEMS sensors and available either in analogue 4-20mA output or digital RS485 ModBus version. Both solutions grant good performances in terms of accuracy and thermal dependence. APPLICATIONS Landslides Tunneling Diaphragm walls Dams Deep excavations Unstable slopes Piles FEATURES Removable and modular system for multiple installation High accuracy Low thermal drift Available in both digital and 4-20mA version Real time monitoring with OMNIAlog datalogger Meet the essential requirements of the EMC Directive 2004/108/EC IN-PLACE INCLINOMETERS 2

6 Landslide application After a number of manual inclinometer surveying, the sliping surface is identified. Therefore is possible to organize an automatic monitoring by installing IPIs in the vicinity of the sliping surface dept and one IPI in the bottom point of each casing as reference.
