AKF398B High Reliable Industrial MEMS Based 2000Hz Vibration Sensor The AKF398 triaxial accelerometer is a voltage output type
accelerometer independently developed and produced by RION
Technology, which can be used in many fields such as vibration test
and impact test. The product adopts analog voltage output,
different address codes can be set, and multiple sensors are
connected in series for a long distance, which is convenient for
multi-point measurement and data analysis. AKF398 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. PRODUCT FEATURES - Three axis (X,Y,Z)
