AKM392 three-axis vibration sensor is a widely used product
independently developed , 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.
