可编程数字振动传感器 Programmable Digital Vibration Sensor
GENERAL DESCRIPTION
The S16220 iSensor® is a digital vibration sensor that combines industry-leading iMEMS® sensing technology with signal processing, data capture, and a convenient serial peripheral interface SPI. The SPI and data buffer structure provide convenient access to wide-bandwidth sensor data. The 22 kHz sensor resonance and 100.2 kSPS sample rate provide adequate response for most machine-health applications. The averaging/decimating filter provides optimization controls for lower bandwidth applications.
