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.

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.
