AXO®301
High-Resolution inclinometer and accelerometer
Inclinometer sensor with high stability under vibrations
AXO®301 is a ±1 g high resolution, single axis closed-loop digital MEMS accelerometer and inclinometer that offers a performance equivalent and cost-effective alternative to precision quartz accelerometers at a fraction of their size, weight and power.
AXO®301 is perfectly suited to acceleration and inclination measurements for applications operating in highly vibrating environments, such as land and railway positioning and navigation systems.
The 24-bit digital SPI interface eases the integration of AXO®301 into high performance IMU and INS. The built-in self-test ensures initial verification of the sensor’s integrity and continuous in operation functionality test.
Inclination measurement accelerometer for railway and industrial applications
AXO301 high resolution MEMS accelerometer and inclinometer is tailored to IMU for train odometry, train acceleration and train tilt measurement, as well as INS for GNSS-assisted positioning and navigation of trains. It is compliant with EN61373 railway standard for vibrations and shocks.
Besides, AXO301 is the perfect candidate for integration into high resolution static and dynamic inclinometers, and motion control systems in construction machinery.
