AKF390 MEMS VOLTAGE VIBRATION SENSOR.pdf
General Description
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.
