STIM210代表著全世界性能最佳的硅MEMS陀螺儀模塊，對于一直迫切地想要提供更小巧、優(yōu)質(zhì)和便宜的解決方案的系統(tǒng)設計者而言，這是一項重大的突破。STIM210是一款成本和能耗低、重量輕而可靠度高的3軸陀螺儀模塊。
STIM210的重量只有55克，工作溫度范圍內(nèi)的零偏穩(wěn)定性為10度/小時，零偏不穩(wěn)定性為0.5度/小時。系統(tǒng)設計者會毫不猶豫地選擇該產(chǎn)品來替代大且昂貴、脆弱且易磨損的現(xiàn)用光纖陀螺儀(FOG)和機械陀螺儀傳感器。
Sensonor Technologies一直致力于拓展MEMS陀螺儀的范圍并研發(fā)一整套全面的高性能慣性傳感器組合，而STIM210正是公司發(fā)展過程中的又一個里程碑。
STIM210不受“國際武器販運條例”(ITAR)限制，適用于工業(yè)、航空航天和國防市場的平臺導航、導引和穩(wěn)定應用。
Sensonor Technologies負責銷售和營銷的副總裁Hans Richard Petersen先生表示：“STIM210是我們成功之路上堅實的一步，實現(xiàn)了我們?yōu)槭袌鎏峁└�(wěn)定、堅固和經(jīng)濟的高性能陀螺儀的愿景。MEMS陀螺儀的性能不斷提高。在苛刻的環(huán)境中，它有更低的成本、更高的堅固性和可靠度。STIM210讓我們的產(chǎn)品組合可以更好地應對導航和導引領域的更多應用。”
STIM210將于從6月6日開始的一周在德國Sensors and Test和美國傳感器博覽會(Sensors Expo)上推出。

Performance
Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements. The unit runs off a single +5V supply and communicates via a "plug & play" high-level RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sampling frequency, LP filter -3dB frequency and RS422 bit-rate and protocol parameters.
For more advanced users, STIM210 may be put in Service Mode. In this mode all the configuration parameters can be intermediately or permanently changed by overwriting the current settings in the flash memory. Service Mode also provides the ability to perform single measurements, perform diagnostics and obtain a higher detail in the status byte.
