AKF398 Analog Devices Three Axis Accelerometer Sensor Low Frequency Vibration

AKF398 Analog Devices Three Axis Accelerometer Sensor Low Frequency Vibration

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.
