▶PRODUCT INTRODUCTION
The AKF398 triaxial accelerometer is a voltage-output accelerometer
independently developed and produced by RION Technology. It is widely used in applications such as vibration testing and
impact testing. The product features an analog voltage output, with
configurable address codes, allowing for multiple sensors to be
connected in series over long distances, making it convenient for
multi-point measurements and data analysis.
The AKF398 uses a single crystal silicon capacitive sensor, consisting of a
micro-machined silicon chip, a low-power ASIC for signal
conditioning, a microprocessor for storing compensation values, and
a temperature sensor. This design ensures low power consumption,
calibrated performance, robust structure, and stable output. The
new electronic configuration provides solid-state power for resets
and comprehensive protection against over-voltage conditions.
With its sturdy construction, low power consumption, and excellent
deviation stability, the AKF398 ensures reliable product output for a wide range of applications.
