AKM390 Triaxial Accelerometer, Analog Output, Silicon Capacitive
Sensor
Product Description:
AKM390 tri-axial accelerometer is a widely used acceleration sensor
products independently developed and produced by RION Technology,
which can be applied to vibration testing, impact testing and other
fields. The product is analog voltage output and can be set with
different address codes. Multiple sensors can be connected in
series for a long distance, which is convenient for multi-point
measurement and data analysis. The AKM390 is a monocrystalline
silicon capacitive sensor. It consists of a silicon chip processed
by micromachining, a low-power ASIC for signal adjustment, a
microprocessor for storing compensation values, and a temperature
sensor. This product has low power consumption, solid structure and
stable output after calibration. The new electronic configuration
provides solid state power for reset and full protection against
over-current. The accelerometers have the characteristics of solid
structure, low power consumption and excellent deviation stability
to ensure the reliability of product output.
