MEMS accelerometer from TDK deliver precision in tough environment

The new closed loop mems accelerometer from TDK serves the need of high precision and the ability withstand tough environmental conditions of severe temperature variation and vibration. The industrial grade AXO315 features one-year composite bias repeatability of 1 mg and composite scale factor repeatability of 600 ppm. It can be used in inertial measurement units and inertial navigation systems in transportation, construction and industrial applications. Designed to work in the temperature range of -55 °C to +105 °C, and 4 g vibrations, surfacemount packaged AXO315 features 24-bit digital SPI interface deliver quartz accelerometers and mechanical inclinometers' performances and exceeds commercial MEMS sensors. In-plane linear accelerometer AXO315 features ±14 g range, very good bias instability of 4 µg, a velocity random walk of 0.006 m/s/√h, and very low noise of 15 μg/√Hz, thus enabling high resolution and low error. Weighing 1.4 grams, hermetic J-lead ceramic packaged with dimensions of 12 x 12 x 5 mm, AXO315 offers size, weight, and price advantage over quartz sensors while remaining free from dual-use export control according to Annex 1 of Council Regulation (EC) No 428/2009. AXO315 delivers an 80% gain in temperature stability compared to Tronics’ previous accelerometer generation AXO215. The new accelerometer complements the existing lineup of Tronic...
