AKF398 CE MEMS Based Accelerometer Sensor 20mA Current Vibration measurement
The AKF398 triaxial accelerometer, developed by RION Technology, is
a voltage-output sensor ideal for applications such as vibration
and impact testing. It features analog voltage output and supports
configurable address codes, enabling multiple sensors to be
connected in series for long-distance, multi-point measurement and
data analysis.
Built with a single crystal silicon capacitive sensor, the AKF398
includes a micro-machined silicon chip, low-power ASIC for signal
adjustment, a microprocessor for compensation storage, and a
temperature sensor. This design ensures low power consumption,
accurate calibration, robust structure, and stable output.
The advanced electronic configuration provides solid-state power
for reset and comprehensive over-voltage protection. With excellent
stability and reliability, the AKF398 delivers consistent
performance in demanding environments.
