CRS09 Technical Datasheet Analogue Angular Rate Sensor www.siliconsensing.com High Performance MEMS Gyroscope Features 1 General Description Proven and Robust silicon MEMS vibrating CRS09 provides the optimum solution for rate range ring structure applications where bias instability, angle random walk and low noise are of critical importance. FOG-like performance Low Bias Instability The latest inductive MEMS gyro sensor element Excellent Angle Random Walk is combined with precision discrete electronics to achieve high stability and low noise, making Low noise the CRS09 a viable alternative to bre-optic and Precision analogue output dynamically tuned gyros. Wide range from -40C to +85C An on board temperature sensor and the resonant High shock and vibration rejection frequency of the MEMS enables additional external Temperature sensor output for precision conditioning to be applied to the CRS09 by the thermal compensation host, enhancing the performance even further. Test MEMS frequency output for precision thermal data for Bias and Scale Factor can be provided with compensation each gyroscope enabling this compensation to be RoHS Compliant implemented without the need for further calibration. Two rate ranges, two performance options Typical applications include downhole surveying, for each precision platform stabilization, ship stabilisation, ship guidance and control, autonomous vehicles and Applications high-end AHRS. Platform Stabilization Whatever your application, the unique and patented Precision Surveying silicon ring technology gives advanced and stable Maritime Guidance and Control performance over time and temperature, overcoming mount sensitivity problems associated with simple Gyro-compassing and Heading Control beam or tuning fork based sensors.
