NA-AMDI Series Three-Axis Digital Accelerometer.
The NA-AMDI series three-axis digital accelerometer consists of two product lines: general-purpose and high-precision. Adopting advanced MEMS technology, this sensor accurately measures the three-axis acceleration of moving carriers through signal conditioning, A/D conversion, digital filtering, as well as temperature and installation error compensation. It boasts excellent performance, cost-effectiveness, high reliability, and robust packaging. Equipped with a temperature sensor output and Self-Test function, it enables precise temperature compensation and Built-In-Test (BIT) capabilities, ensuring stable and reliable operation in various complex environments.
Typical Applications
- Motor monitoring, train monitoring, earthquake prediction, geological monitoring, aircraft testing
- Navigation and guidance, building deformation monitoring, collision testing, calibration of vibration and shock test benches
