1. INTRODUCTION
The Geokon Model 6160 MEMS Tilt Sensor is designed for permanent long-term monitoring of
changes in tilt of structures such as dams, embankments, foundation walls, retaining walls,
buildings, and the like. There are two main types of Tilt Sensors: The Model 6160 is an adaption
of the tiltmeter used in Model 6150 In-Place Inclinometer, and the 6161 utilizes the same MEMS
sensors inside a Nema 4 enclosure. Both types are shown in Figures 1 and 2. Each style of
housing contains either one MEMS, (micro-electrical-mechanical-system), sensor, or two MEMS
sensors oriented at 90 degrees to measure biaxial tilts. All types include a thermistor for
measuring temperatures.
They are designed to be attached to the structure so that they can sense and measure any tilting of
the structure in uniaxial or biaxial directions. Angular changes of as little as 2 arc seconds can be
detected.
