STIM210代表著全世界性能最佳的硅MEMS陀螺儀模塊，對(duì)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(shè)計(jì)者而言，這是一項(xiàng)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(shí)，零偏不穩(wěn)定性為0.5度/小時(shí)。系統(tǒng)設(shè)計(jì)者會(huì)毫不猶豫地選擇該產(chǎn)品來(lái)替代大且昂貴、脆弱且易磨損的現(xiàn)用光纖陀螺儀(FOG)和機(jī)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(guò)程中的又一個(gè)里程碑。
STIM210不受“國(guó)際武器販運(yùn)條例”(ITAR)限制，適用于工業(yè)、航空航天和國(guó)防市場(chǎng)的平臺(tái)導(dǎo)航、導(dǎo)引和穩(wěn)定應(yīng)用。
Sensonor Technologies負(fù)責(zé)銷(xiāo)售和營(yíng)銷(xiāo)的副總裁Hans Richard Petersen先生表示：“STIM210是我們成功之路上堅(jiān)實(shí)的一步，實(shí)現(xiàn)了我們?yōu)槭袌?chǎng)提供更穩(wěn)定、堅(jiān)固和經(jīng)濟(jì)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(jiān)固性和可靠度。STIM210讓我們的產(chǎn)品組合可以更好地應(yīng)對(duì)導(dǎo)航和導(dǎo)引領(lǐng)域的更多應(yīng)用。”
STIM210將于從6月6日開(kāi)始的一周在德國(guó)Sensors and Test和美國(guó)傳感器博覽會(huì)(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.
