AKG392 three-axis vibration sensor is a product independently
developed and produced, 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
Vibration sensor 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.
