▶ INTRODUCTION
AKS392 triaxial accelerometer is a product independently developed and produced by Rion Technology,
which is specially used in the building monitoring industry. In order to improve the resolution of the
product, the product uses a smaller range, which can more accurately reflect the subtle changes of the
product. Digital interface output is adopted, RS232/485/TTL is optional, different address codes can be
set, and multiple sensors are connected in series for a long distance, which is convenient for multi-point
measurement and data analysis. The internal FFT processing can directly output the vibration frequency,
speed and amplitude of the object, which is convenient for users to analyze the data. The AKS392 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-powering.
The long-term stability and deviation of the scale factor are typically less than 0.1% over the full scale
range. This series of products have the characteristics of solid structure, low power consumption and
excellent deviation stability, which ensures stable output reliability

▶ VIBRATION PARAMETER INDEX
The product's vibration frequency, speed, and displacement are derived from data analysis, where frequency is the main frequency of the current object vibration frequency, speed is the maximum vibration speed, and displacement is the maximum amplitude value of the object vibration. Because of the irregularity of the object vibration, the data is only used reference.
