New MEMS Tilt Beam

The Model 6165 MEMS Tilt Beam is designed for attachment to structures, on either a vertical or horizontal surface, for the measurement of any tilting or differential settlements that may occur. The Tilt Beams can be coupled together in long horizontal strings to measure differential settlement along embankments, railroad tracks, pipelines, tunnels, etc., or they can be used in vertical strings to measure the horizontal deformation of retaining walls, sheet piling, etc.

The Tilt Beam contains a Micro-Electro-Mechanical-System (MEMS) sensor which offers a range of ±15°, with high-sensitivity and accuracy. The MEMS sensor is mounted inside a fiberglass, aluminum or anodized aluminum channel equipped with lugs for mounting to the structure under study. MEMS tilt sensors have very good long-term stability, are virtually immune to shock loading and have very low thermal coefficients. They are low-cost, robust and readily adaptable to automation and remote monitoring for profiling in real-time.
