Page 2: Specification
The d-Tilt/BluTuilt features full (360 arcdeg) tri-axial measurement so that placement on structures does not require precise leveling. The d-Tilt/BluTilt can be attached to a beam or mounted directly to any structure. The d-Tilt/BluTilt is also available in borehole model (shown) with a 38mm OD. - Page 3 Generalized 3-D Rotation An accelerometer measures the orientation with respect to the gravity vector which for a cartesian coordinate system (Fig 1) is given by : ) ………(1) g = ( −1 The measured acceleration values are given by a = �� . �� ……..(2) where R is a generalized rotation matrix recognizing that the coordinate system is right handed.

Page 4: Installation
Installation The BluTilt uses a 3-axis accelerometer to measure the orientation of the gravity vector g [0,0,- g]. As stated above, this does not mean that the device can measure complete 3-D movements (pitch, roll, yaw) since rotations in the horizontal plane (yaw) cannot be resolved with respect to the vertical gravitational vector. - Page 5 The raw data from the accelerometer is a 20-bit result varying from 256,000 (+1g)to -256,000(-1g). The values for the three axes, x,y and z are reported. tilt_mode 1 - Vector mode: Another way to define a tilt is to specify (i) a single tilt angle () and (ii) a vector (n) representing the axis of rotation (see NXP app note section 4).
- Page 6 In many situations the user will want to monitor changes in tilt from an arbitrary reference following installation. To set a reference tilt (a ) the user should install the Blutilt and allow time for the installation to stabilize. Outputing the custom command tilt_ref_set will save the current...
- Page 7 The data payload is populated by the two angles corresponding to pitch and roll. For clarity these are remapped as X, Y, Z along the x,y and z axes of the BluTilt. The sign is positive for downward rotation from the positive end of the axis. Field 5 of the output string is the tilt_z_up...

- Page 17 Step3 With a wire brush, compressed air or vacuum clean out the hole of all dust created during the drilling process. Step 4: Coat the base of the BluTilt enclosure with either a structural adhesive or silicone.
- Page 18 Step 5: Use 4 Tapcon screws either 1.5” or 2” long, to tightly secure the BluTilt. Align the hole in the fixture over the hole in the base material. Insert the concrete screw through a hole in the fixture and into the hole in the base material.
