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. This is used in critical applications where real-time monitoring and early warning is required in order to protect life and valuable assets.

The in-place inclinometer system consists of a string of digitalinclination sensors. This string of sensors is positioned inside the inclinometer casing to span the movement zone. Each in-place inclination sensor is fitted with a pair of pivoted sprung wheels.

The digital in-place sensors areconnected 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 the model ESDL-30 datalogger (without any need of multiplexer). 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 ESDL-30 datalogger transfers the logged data via GPRS/GSM network to a central or cloud server.
