Product Description

AKM398 triaxial accelerometer is a widely used acceleration sensor independently developed and produced by RION Technology, which can be applied to vibration testing, impact testing and other fields. The product adopts analog current output and can be set with different address codes. Multiple sensors are connected in series for a long distance, which is convenient for multi-point measurement and data analysis. The AKM398 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 products have features as rugged construction, low power consumption, and excellent bias stability to ensure outstanding output reliability.
