Silicon Sensing Systems has launched two new silicon MEMS angular rate sensors, CRG20 and CRS09, which are based on a patented silicon ring gyro technology.

Derived from technology used in the automotive industry, the CRG20 device uses full digital closed-loop control, which the supplier claimed can eliminate any temperature and aging effects associated with analogue devices.

There is also built-in temperature compensation.

The CRS09 angular rate sensor is targeted at applications such as stabilisation, navigation and testing. It uses a combination of a silicon MEMS gyro and discrete electronics.

The devices temperature stability, and the provision of both internal temperature and silicon ring frequency data as additional outputs, allow very accurate calibration of the gyro over its operating temperature range.

CRS09 is suitable for platform stabilisation, measurement and test, and high-performance general aviation applications such as AHRS.
