CAN angle sensor
TK Engineering and Cobo (Finland and Italy) have developed the AMU-GEO 360 CAN angle sensor. It is suitable for boom mounting, with gyro-aided compensation of vibration, linear acceleration, and shock.
The CAN angle sensor is intended for excavator type, fast moving crane booms where the centrifugal forces and shocks are considerable and accelerometer-based sensors cannot be used. With its CANopen interface and a CiA 410 inclinometer device profile, the sensor is suited for integration into new and existing systems. The AMU-GEO 360 uses a 6-axis-of-freedom sensor (solid state accelerometer and gyroscope) and software algorithms to create a 360° angle measurement free of shock, vibration, and centrifugal acceleration.
Using these techniques, the sensor’s accuracy is better/equal to ±0,7° in dynamic conditions and in static conditions ±0,3° can be achieved in the entire working range (0° to 360°). Due to its operating temperature of -40 °C to +80 °C and power supply range of 8 VDC to 32 VDC, the IP67-rated sensor is suitable for harsh mobile applications.
The basic communication services comply with CiA 301 and CiA 305. The inclinometer-specific interface complies with the CANopen device profile for inclinometers, CiA 410. The physical layer meets ISO 11898-2 and the M12 connector follows the CiA 303-1 pinout. The standardized interface enables an upgrade of the existing uncompensated inclinometers.
