MEMS accelerometer from TDK deliver precision in tough environment
Date: 15/12/2020
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/vh, and very low noise of 15 µg/vHz, 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 Tronics high performance GYPRO® digital gyros for high-performance IMUs and INS. It comes in a lightweight 1.4 g hermetic SMD J-lead ceramic package (12 x 12 x 5 mm), enabling low-cost assembly and reliability on PCB, even in fast-changing temperature conditions.
Tronics high performance GYPROs and this new AXO315 suggested for applications such as servo inclinometers and dynamic inclinometers in industrial motion control units, IMUs and INS for GNSS-aided positioning, and navigation of manned and unmanned ground vehicles and trains.
The AXO315 accelerometers, made and tested at Grenoble, France are sampling now with full production scheduled for summer 2021. Arduino-based evaluation kit are provided for evaluation.
