AKM390 Triaxial Analog Output, Silicon Capacitive Sensor
Product Description:
The AKM390 three-axis Vibration sensor is a widely used acceleration sensor series product
independently developed and produced, which can be applied in
multiple fields such as vibration testing and impact testing. The
product adopts analog voltage output. AKM390 is a single crystal
silicon capacitive sensor, consisting of a silicon chip that has
undergone micro mechanical processing, a low-power ASIC for signal
adjustment, a microprocessor for storing compensation values, and a
temperature sensor. This product has low power consumption, has
been calibrated, has a sturdy structure, and stable output. The new
electronic configuration provides solid-state power for reset and
comprehensive protection against over voltage. This series of products features sturdy structure, low
power consumption, and excellent deviation stability, ensuring the
reliability of product output.
