AKF390 MEMS VOLTAGE VIBRATION SENSOR.pdf
The AKF390 triaxial VIBRATION SENSOR is a voltage output type
VIBRATION SENSOR independently developed and produced, which can be
used in many fields such as vibration test and impact test. The
product adopts analog voltage output, AKF390 is a single crystal
silicon capacitive sensor, which consists of a silicon chip
processed by micro-machines, a low power ASIC for signal
adjustment, a microprocessor for storing compensation values, and a
temperature sensor. This product has low power consumption,
calibrated, sturdy structure and stable output. The new electronic
configuration provides solid-state power for reset and
comprehensive protection from over-voltage. The products have the
characteristics of sturdy structure, low power consumption,
excellent deviation stability, etc., to ensure the reliability of
product output.
