CRH02 Gyroscope (unpackaged)

Compact, high performance single axis gyroscope, providing outstanding stability with low noise

CRH02 (OEM) provides the optimum solution for OEM customers with applications where bias instability, angle random walk and low noise are of critical importance.
At the heart of CRH02 (OEM) is Silicon Sensing’s VSG3QMAX vibrating ring MEMS sensor which is at the pinnacle of 15 years of design evolution and the latest off a line which has produced over 30 million high integrity MEMS inertial sensors. The VSG3QMAX gyro sensor is combined with precision discrete electronics to achieve high stability and low noise, making the CRH02 (OEM) a viable lower cost MEMS alternative to Fibre-Optic Gyro (FOG) and Dynamically Tuned Gyro (DTG).
An on board temperature sensor and the resonant frequency of the MEMS enables additional external conditioning to be applied to the CRH02 (OEM) by the host, enhancing the performance even further.
