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
