Digital Vertical Inclinometer System

The digital inclinometer system consists of a traversing type digital Bi-axial tilt sensing probe that is connected to a reelunit kept at borehole top. The reel unit consists of a winding reel that holds the cable and a wireless Bluetooth relayunit that sends the digital probe data to the mobile phone. A rechargeable battery in the reel unit supplies power to thewhole system. The digital inclinometer probe has a measuring range of ± 30 degrees with a resolution of ± 10 arc seconds. The probeuses a 24 bit ADC that measures the MEMS sensor output with a resolution of over 1 million counts. An embeddedprocessor in the probe provides a digital output that gives the horizontal displacement value directly in desiredengineering units. Applications• Determination of lateral deformation/ horizontal movement and deformation of earth works or structure• Measurement of magnitude of tilt or inclination and its variation with time in structures like diaphragm/retainingwalls, piles etc.
