The Racelogic Yaw sensor with CAN and serial output houses a single axis MEMs Yaw rate sensor, and a twin axis G-sensor. The Yaw sensor can measure ±150º/s, and the accelerometers can measure ±1.7g. Inside there is also a temperature sensor.

Each Yaw rate sensor is calibrated on our stabilised turntable in an environmental chamber, so that a full temperature calibration is carried out from -20 to +50ºC. This gives the Yaw rate sensor a very high stability of less than 70º per hour.

This sensor can be used either directly connected to a VBOX, or it can also be used as a stand alone device, with the CAN output fully configurable by the end user.

The maximum sample rate of the IMU is 100Hz, and the sensor connects directly to a VBOXII or VBOXIII to measure Pitch rate, Roll rate, Yaw rate, Longitudinal accel, Lateral accel and Vertical accel.

The difference between a good IMU and a bad one is the quality of the temperature calibration process.

To obtain the best results, we have invested in a state of the art environmental chamber, and installed a precision stabilised turntable. We calibrate using 12 different temperature steps, and the whole process for all three axis takes 18 hours, resulting in a very stable sensor.

In the final product, the sensors are over sampled at 500Hz to reduce noise, and the internal A-D on each channel is 24 bits.

This sensor can be used either directly connected to a VBOX, or it can also be used as a stand alone device, with the CAN output fully configurable by the end user.
