AKM392 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 digital interface output, RS232/485/TTL is optional, and different address codes can be set. Multiple sensors are connected in series for a long distance, which is convenient for multi-point measurement and data analysis. The AKM392 is a monocrystalline silicon capacitive sensor consisting of a micromachined silicon chip, a low-power ASIC for signal conditioning, 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, providing protection against over-current. The long-term stability and deviation of the scale factor are typically less than 0.1% over the full scale range. This product has the characteristics of solid structure, low power consumption and excellent deviation stability, which ensures stable output reliability.
