DESCRIPTION STIM210 is a multi-axis gyro module with up to 3 axes of highly accurate MEMS gyros. Each axis is factory calibrated for bias and sensitivity, and compensated for temperature effects. This new design of the STIM200-series allows for an improved bias error over temperature (10°/h) and an improved non-linearity (nom. 50ppm BSL over FS). STIM210 industrialization is realized by combining the well proven Sensor ButterflyGyroTM technology with a full digital operation. Input range, orthogonality and output formats The STIM210 full-scale angular rate input range is 400°/s. 3-axis modules feature electronic axis alignment, further improving orthogonality between axis (down to 1mrad). Selectable output formats are angular rate, increment angle, average angular rate and integrated angle, at sampling rates up to 2000 samples per second. Reliability and robustness STIM210 modules have MTBF > 120k

hours per axis (according to MIL-HDBK An add-on PCI card for the kit is also 217), outperforming current FOG systems. available (this is recommended for extensive testing and characterization). Perfect tuning of excitation and detection The connector of the PCI card is directly frequencies, as well as perfectly balanced pin compatible with the plug of the vibrational masses, result in very low STIM210 communication cable of the kit, vibration and shock sensitivity thus enabling an easy alteration between (1500g/0.5ms sine) in any direction. usage of USB cable and PCI card when Power and Interface required.
