The AXO315 accelerometer utilizes a force-rebalance architecture, featuring a 24-bit digital SPI interface and a compact SMD design. Its performance rivals that of traditional analog quartz accelerometers and mechanical inclinometers, yet it is substantially smaller, lighter, and more cost-effective. Additionally, it surpasses all available MEMS sensor components, simplifying integration compared to analog alternatives.

Remarkable 1mg Composite Bias Consistency in Dynamic Settings

With a one-year composite bias repeatability of just 1 mg, the AXO315 maintains a 600 ppm composite scale factor repeatability across a temperature range of -55 °C to +105 °C, even under vibrations exceeding 4 g. Its remarkable vibration rejection capabilities enhance performance, supported by superior Allan variance characteristics, which include a basis instability of 4 µg, a velocity random walk of 0.006 m/s/√h, and a minimal noise level of 15 µg/√Hz, ensuring high resolution and low error rates.

Ideal for High-Performance IMU, INS, and AHRS Applications

The AXO315 is engineered for precision and reliability in demanding environments, capable of enduring extreme temperature and vibration conditions typical in sectors such as rail transport, avionics, oil and gas, and various industrial applications.

This device enhances the existing range of high-performance Tronics GYPRO® digital gyroscopes, allowing for a meaningful reduction in size, weight, and material costs for INS, IMU, and AHRS systems in dynamic applications.
