Widely Using Triaxial MEMS Accelerometer Sensor With Firm Structure & Stable Output For Vibration and Impact Test

General Description

AKE390B voltage type accelerometer sensor series products isRION company imported the Switzerland patented technology to produce for using widely, suitable for vibration testing, impact testing and more fields. This series products with firm structure,low power consumption, excellent deviation stability .etc characteristics to guarantee the reliability of outstanding output .

AKE390B is a monocrystalline silicon capacitive sensor, composed by a silicon chip of micro-mechanical treatment, low power ASIC for the signal adjustment, a microprocessor for storing compensation value and a temperature sensor. The product with low power consumption, after calibration, firm structure, stable output . New electronic configuration reset to provide a solid-state power, to provide comprehensive protection for overcurrent. Scale factor in the full range of long-term stability and the deviation is typically less than 0.1%.
