Portable MEMS-based system for monitoring changes in inclination of structures using permanently installed tilt plates.
The Geolook MEMS Portable Tilt Meter is a lightweight, rugged instrument designed to measure the inclination of structures such as retaining walls, concrete dams, and buildings. Unlike fixed-in-place sensors, this system consists of a portable probe and a series of reference "tilt plates" bonded to the structure. To take a reading, the operator places the probe onto the keyed tilt plate. The internal MEMS (Micro-Electro-Mechanical Systems) accelerometer instantly measures the angle of tilt with high precision. This allows a single instrument to cost-effectively monitor hundreds of points across a project site.

The system relies on 'Tilt Plates'—small circular discs made of ceramic or stainless steel—that are epoxy-bonded or screwed onto the structure at points of interest. These plates have four keyed pegs to ensuring the probe is positioned in exactly the same orientation every time.
During a survey, the operator mates the portable tilt meter to the plate. The internal MEMS sensor measures the angle of the plate relative to gravity. By subtracting the initial baseline reading from the current reading, the change in tilt (rotation) is calculated in millimeters per meter or degrees.
The primary advantage of this system is cost. Instead of buying 50 expensive sensors and 50 data loggers for a building, you only buy 50 inexpensive tilt plates and 1 portable meter. This makes it the standard choice for projects requiring broad coverage on a limited budget.
Historically, these instruments used delicate servo-accelerometers. The G76-Y950 uses modern MEMS technology, which offers comparable accuracy but with significantly higher durability and shock resistance.
This makes the unit much more robust for daily construction site usage, where accidental drops or rough handling can occur.
