CRM100 und CRM200 bilden eine Serie von Silizium-MEMS-Gyroskopen auf Chip-Ebene von Silicon Sensing, die rauscharme Winkelgeschwindigkeitsmessungen in einem kleinen oberflächenmontierten Gehäuse anbieten. Der CRM100 wird flach auf einer Platine montiert, während die CRM200-Version seitlich montiert wird, was in Kombination die Messung der drei Freiheitsgrade (Rollen, Nicken und Gieren) mit einer einzigen Platine ermöglicht.
Eigenschaften
- Proven and robust 5th generation vibrating structure gyro technology (VSG)
- Class-leading bias and noise over temperature for precise dead reckoning navigation and pointing
- Planar and orthogonal packages (CRM100 and CRM200)
- User-selectable dynamic ranges; 75°/s, 150°/s, 300°/s, 900°/s (max 1,000°/s)
- High rate range version (up to ±2,700°/s) also available
- High bandwidth low noise
- Small (CRM100: 5.7 x 4.8 x 1.2mm, CRM200: 6.3 x 5.5 x 2.7mm)
- User adjustable bandwidth (to 160Hz)
- Analogue and Digital (SPI®) outputs
- Low power, 3.3V supply, 4mA
- Excellent shock and vibration rejection
- Hermetically sealed SMD package
- Integral temperature sensor
- AEC Q100 tested
