Brief Introduction
MS3012 single/dual/tri-axial MEMS accelerometer sensor is one type of high performance vibration
monitoring sensor base on MEMS technologies. It adopts 7~24V or 5V±3% power supply, integrate X-Y-Z
trial axes and self test function, it adopts high performance accelerometer, the dynamic range can reach
110dB.

MS3012 accelerometer sensor has passed the strictest tests, it enjoys excellent performance in noise,
dynamic range, non-linearity, repeatability, temperature drift, shock proof, etc. this product is an ideal option
for seismic monitor, vibration monitoring, high speed train/metro train, test platform of vibration and
shocking, structure health monitoring, etc.
