Introduction

ER-MA-5 High Accuracy MEMS Accelerometer (Alternative of MS1000)

Accelerometer is an inertial sensor, which can measure the linear acceleration due to gravity. MEMS accelerometer has the characteristics of small volume, light weight and low energy consumption that can be widely used in vibration detection, attitude control, security alarm, consumer applications, motion recognition and status recording. Accelerometers are combined with gyroscopes and magnetometers to create IMU (inertial measurement units).

Applications

Inertial measurement: inertial guidance, overload measurement, combined navigation
Tilt measurement: antenna attitude, platform measurement, dip test
Vibration measurement: mechanical equipment, bridge dam, safety test
