▶ INTRODUCTION
The AKG392 triaxial accelerometer is a new accelerometer
independently developed and produced by Rion Technology applied in
wide range of applications, which covers many fields such as
vibration testing and impact testing. The product adopts digital
interface output with options as RS232/485/TTL. Different address
codes can be set, multiple accelerometers can be installed in
series for long distance, which is convenient for multi-point
measurement and data analysis. Internal FFT processing can directly
output the object vibration frequency and speed and Amplitude,
convenient for users to analyze data.
The users can change the sampling frequency according to the actual
frequency of the object to improve the frequency measurement
accuracy. AKG392 is a single crystal silicon capacitive sensor,
which consists of a silicon chip processed by micro-machines, a
low-power ASIC for signal adjustment, a microprocessor for storing
compensation values, and a temperature sensor. This product has low
power consumption, calibration, sturdy structure, and stable
output. The new electronic configuration provides solid-state power
for reset and protection from over-voltage. The long-term stability
and deviation of the scale factor in the full-scale range are
typically less than 0.1%. This series of products have the
characteristics of sturdy structure, low power consumption, and
excellent deviation stability, ensuring 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.

| Speed | Vibration speed | m/s |
| Amplitude | Vibration amplitude value | m |
| Frequency | 0~500 | Hz |
