AKG394 Vibration Amplitude Sensor
▶ 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 displacement, convenient for users to analyze data. The vibration, frequency, speed, and displacement of objects below 4HZ are uncertain values and have no reference value. 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.
