Wireless In-place Inclinometer (IPI) System

Model EAN-52MV Overview

Encardio-rite model EAN-52MV is a wireless in-place inclinometer (IPI) system, designed to measure the lateral movement of earthworks or structures. The IPI is used in critical applications where real-time monitoring and early warning are required in order to protect life and valuable assets.

The in-place inclinometer system consists of a string of digital tilt sensors. The string of tilt sensors is positioned inside the inclinometer casing to span the movement zone. Each tilt sensor is fitted with a pair of pivoted sprung wheels. Model EAN-52MV IPI consists of tilt sensors with SDI-12 output.

The tilt sensors are connected through a single 3 conductor bus cable in a daisy chain fashion, connecting each sensor to its next immediate neighbor and finally to the top of the borehole and directly to a suitable datalogger. This has a great advantages at locations with large number of sensors in a borehole, as it eliminates the hassle to accommodate large number of individual signal cables inside the borehole.

The Encardio-model ESDL-30 datalogger can be used with model EAN-52MV IPI system.
