The Best Open-loop MEMS Accelerometer Displacing Traditional High Cost, Fragile Solutions



New accelerometer RS9010 has been presented at Sensor+Test, Nuremberg, 26-28 May 2009 at Sensors Expo Rosemont, IL, 8-10 June 2009 by Colibrys.


The company launched the IRIS accelerometer family, world’s best open-loop MEMS accelerometer, to displace traditional vibrating quartz and electromechanical solutions. MEMS establishes a new competition to historical high-end motion sensors, as typically offered by Honeywell, by pushing the boundaries of its performances, offering higher robustness at reduced cost in safety critical and harsh environment applications.


The first product released based on IRISTM technology is RS9010.A. This ±10 g sensor specifically designed for AHRS (Attitude Heading and Reference Systems) and mid accuracy navigation application offers an order of magnitude improvement over existing leading MEMS technology and now seriously compete with traditional vibrating quartz and electromechanical solutions. This product uses an open loop electronic interface, specifically designed for long term stability. The enhanced sensor design provides an overall composite repeatability of bias better than 1.5mg (17) for ±1 0g and a scale factor repeatability of 500 ppm (17). The vibration rectification coefficient is 150 µg/g˛.


“RS9010 will enable the AHRS designers to obtain excellent performance at reduced cost while benefitting from the inherently rugged MEMS sensor, which open new application opportunities and simplifies sensor handling during the manufacturing process” commented Soheil Habibi, Business Development Manager for Colibrys inertial sensors.


He added further “IRISTM is a big step forward in realizing our vision to commercializing µg stability accelerometers with high shock resistance and high operating temperature, displacing the established vibrating quartz and electromechanical solutions. We believe that in near future, we will have µg stability accelerometers and high stability gyros based on MEMS technology, enabling a wide range of existing and new applications in the Defense and Aerospace markets”.
