The inclinometer is designed to accurately measure inclination angles in two directions X and Y in the range of ±80º. The CANopen® device profile for inclinometers [DS-410], defines the X-axis as the longitudinal measurement, and the Y-axis as the lateral measurement. For both axes, the range of measurement is up to ±80º. If vertically installed, the sensor can also measure an inclination angle in one sensing direction in the ±180º (0-360º) range.
The angles are measured by a two-axis MEMS sensor, which senses acceleration caused by the gravity force in two orthogonal directions. The sensor provides two output signals corresponding to each sensing direction. The output signals from the MEMS sensor are normalized and processed by a powerful microcontroller to receive inclination angles. The resolved angles can be then sent to the CAN bus.
The inclinometer is designed to not only comply with the CANopen® profile, but to also support a variety of extra features that makes it a more versatile sensor. Several of the optional Communication objects outlined in DS-301 are supported by the Inclinometer beyond those referenced in the device profile DS-410. The unit has user programmable functionality using SDO object access, per CiA DS-301. An .EDS file is provided to interface to standard CANopen ® tools.
