The BluTilt is a full 360 arcdeg triaxial wireless tiltmeter for very precise measurement (0.001 arcdeg resolution) of changes in inclination. The instrument uses a very low noise MEMS accelerometer that enables a resolution of 0.001 arcdeg with a stability of +/-0.001 arcdeg.
The BluTilt features full (360 arcdeg) triaxial measurement so that placement on structures can be does not require precise leveling. The BluTilt can be attached to a beam or mounted directly to any structure. The BluTilt is also available in borehole model with a 38mm OD.
Based on a low noise MEMS accelerometer, the BluTilt is also available for dynamic monitoring: BluShake

The use of a tri-axial tiltmeter to measure tilt angles is surprisingly complex as outlined in the Application Note from Freescale Semiconductor:

The principles outlined have been incorporated into the functionality of YieldPoint’s BluTilt instrument as explained in the user manual.
