TILLI is a portable tiltmeter composed by a rugged stainless steel frame with aluminium sensor housing containing a self-compensated MEMS accelerometer. The surfaces of the frame are machined to allow an accurate positioning of the tiltmeter during measurements.
When in use, TILLI is placed on the tilt plate which is permanently installed on the structure surface. The bottom surface of the tiltmeter is used with horizontally-mounted tilt plates while the side surface
is used with vertically-mounted tilt plate.
Readings in two orthogonal directions can be obtained rotating
the instrument of 90° only on the horizontal surface. Coniugated measurements (180 degree rotation) eliminate instrumental offset.
