Model CRM100 -Precision Navigation and Pointing Gyroscope
CRM100 and CRM200 form a series of chip-level silicon MEMS gyroscopes from Silicon Sensing, off ering low-noise angular rate measurements in a small surface mounted package. The CRM100 mounts fl at on a board, whereas the CRM200 version is mounted on its side, which when combined, enables the three degrees of freedom measurements (roll, pitch and yaw) to be made with a single board.
Each device comprises a single-axis piezoelectric resonating ring gyroscope with a dedicated control ASIC in a single hermetically sealed ceramic chip scale package. Measurement data can be output via analogue and digital (SPI®) interfaces. Device temperature is available from the digital interface, along with built in test (BIT) status. User-confi gurable rate range options are offered, from 75°/s to 900°/s, and high rate range versions (up to 2700°/s) are also available. Bandwidth up to 160Hz is controlled by choosing a suitable capacitor.
At the heart of the chip scale package is a silicon ring, mounted on a pedestal, and a controlling ASIC. The ring resonates at its natural frequency whenever power is applied to the device. Any device rotation rate is detected as a change to the resonating pattern and output as an analogue voltage proportional to rate, or within the SPI® data stream.
Silicon Sensing Systems is a market leader in silicon MEMS gyroscopes, accelerometers and inertial measurement systems, specialising in high performance, reliability and affordability. With a strong heritage in inertial sensing that can be traced back over 100 years, all sensors are based on in-house patented designs which are produced in its own state of the art MEMS foundry. Silicon Sensing has delivered over 40 million sensors to thousands of satisfi ed customers worldwide, and continues to drive performance through technical expertise and continuous innovation.
