Low Noise Capacitive Mems Accelerometer Sensor
Brief Introduction
MA1000A MEMS accelerometer is the besthigh performance capacitive accelerometer adopting closed loop structure, it useshigh performance ASIC and MEMS sensor to build closed-loop system, andit enjoys excellent performance with low noise, dynamic range, non-linearity, repeatability, temperature drift and shock resistance. MA1000A guarantees confident and accurate vibration measurement in rugged environments.
MA1000A accelerometer also has embeddedself-test function, temperature sensor for compensation and built-in high precision reference voltage, which ensures MA1000A to be the top level of accelerometer around the world. Using tiny sealed LCC20 encapsulation (9*9mm), MA1000A has been widely used in Seismic Monitor, Micro-vibration Monitoring, Engineering Geophysical Exploration, Inertial Navigation, Structure/Building Monitoring, Surface Wave Detection, and Platform Stability, etc. Eachaccelerometer is fully tested and qualified, and its superreliability and excellent performance gains customers' high praise
