Yaw Rate Sensor YRS 3
www.bosch-motorsport.com

This sensor is designed to measure the physical effects of yawing, lateral and longitudinal acceleration.
In order to achieve this, the sensor features both ameasuring element for yaw rate and two for acceleration, with one appropriate integrated circuit.
A rotation around the third orthogonal axis, a yaw rate,
creates a Coriolis force on the accelerometers, which
is detected by the element. Apart from the measuring
element for yaw rate, a pure surface micro machined
measuring element for acceleration is utilized to measure the vehicles lateral and longitudinal acceleration.
This enables a very precise application.
The main feature and benefit of this sensor is its widemeasuring range, the standardized 1 Mbaud/s CAN-signal output and the combination of high quality production part and robust design.
