MEMS Tilt Sensor Featuring Micro g Bias Stability



Colibrys announced the release of one of the world’s highest stability ± 3 g full range accelerometer commercially available, the RS9003.A.


The RS9003 is an ideal sensor designed for tilt measurement, measurement whilst drilling, borehole survey and other drilling applications where precision sensing over time in harsh and safety critical environments is demanded (see Colibrys application note: Down borehole & directional drilling). It is also a perfect product for stabilization of large platforms such as radars, antennas, turrets and surveillance cameras.


The sensor features composite bias stability of better than 600 μg and composite scale factor stability of better than 500 ppm. “This level of performance has been so far the domain of precision mechanics and vibrating quartz accelerometers, which are foreseen to be increasingly displaced by Silicon MEMS technology, offering a disruptive change in tilt sensing performance with major benefits in terms of robustness, size and weight, cost and power consumption” highlights Soheil Habibi, Business Development Manager for Colibrys inertial sensors.


He added further; “We aim to displace electromechanical sensors such as the Honeywell QFlex in many of its Military, Aerospace and Energy markets and RS9003 is one of the building blocks in this process”.


The RS9003 is interfaced with an open loop electronic and is offered in an LCC20 standard ceramic package (8.9 mm x 8.9 mm). The small footprint of this sensor helps system designers to realize extremely precise performance in minimum space available.
