Fixed-in-place biaxial tilt sensor for continuous, automated monitoring of structural rotation.
The Geolook Fixed MEMS Tilt Meter is designed for the permanent, automated monitoring of changes in tilt and rotation of structures. Unlike the portable system which requires manual reading, this sensor is permanently anchored to the structure and hard-wired to a data logger. It utilizes a high-precision MEMS accelerometer to measure tilt in two orthogonal axes (X and Y). The sensor is housed in a rugged, waterproof enclosure suitable for harsh environments. It is often installed on "tilt beams" linked together to monitor differential settlement along the entire length of a wall, railway track, or tunnel.

While the portable tilt meter (G76-Y950) is great for weekly checks, it cannot catch sudden movements. The Fixed MEMS Tilt Meter (G76-Y951) is connected to a data logger that can take readings every minute.
This allows for real-time alarms if a retaining wall begins to rotate dangerously during active construction or excavation nearby.
Modern G76-Y951 units typically use a digital RS-485 signal (Modbus). This allows dozens of sensors to be 'daisy-chained' on a single cable run, significantly reducing cabling costs and simplifying installation in long tunnels or bridges.
A common application is the 'Electro-Level Beam' or 'Tilt Beam'. Sensors are mounted on rigid metal beams (typically 1-3 meters long) which are linked end-to-end along a tunnel wall or railway.
By mathematically combining the tilt angles of each beam, engineers can calculate the exact vertical settlement profile of the entire structure without needing optical surveying.
