AXO315T0 is a single-axis, high-temperature, closed-loop MEMS accelerometer designed for precise inclination measurement in directional drilling applications up to 150°C. It features a hermetic ceramic SMD package, a 24-bit digital SPI interface, and an input range of ±14 g. Operating from -30°C to +150°C, it exhibits a bias temperature error of 0.8 mg and a scale factor temperature error of 500 ppm. Noise density is 10 μg/√Hz at room temperature and 18 μg/√Hz at 175°C, with vibration rectification error of 20 μg/g². The device supports continuous self-test, survives shocks up to 2000 g, and has a rated lifetime exceeding 1000 hours at 150°C. It is REACH and RoHS compliant and non-classified under dual-use export control.
High stability, reliability, and vibration rejection for inclination measurement in downhole navigation up to +150°CAXO315T is a single-axis, high temperature, closed-loop MEMS accelerometer with ±14 g input range that offers a digital, cost-effective, and low-SWaP alternative to quartz accelerometers for precise inclination measurement in directional drilling applications exposed to high temperatures up to +150°C.Its superior vibration rejection enabled by an innovative closed-loop architecture makes AXO315T a perfect candidate for integration into directional modules used for drilling tools guidance under harsh vibrations and shocks. With a lifespan of 1000 hours at 150°C, AXO315T is a reliable MEMS acceleration sensor that maximizes the productivity of oil and gas drilling operations while ensuring precise downhole navigation thanks to its high stability under extreme temperature and vibrations conditions.
