KX134-1211

The KX134-1211 is a capable accelerometer useful for data collection applications and high g environments. It's basically a straight upgrade of the ADXL375, with a similar digital interface but higher resolution and less error.

Sensor Features:

• Measurement Range: Adjustable from ±8g to ±64g
• Resolution: 16 bits, evenly distributed across the complete measurement range
• Data Rate / Averaging Period: Adjustable from 0.78Hz to 25.6kHz

Error Specifications:

• Zero-G Offset (what the chip reads at 0 gs): ±0.075g
• Gain Error (possible scaling factor error on output reading): ±8.0%
• Noise (random noise added to measurement value): 300*sqrt(sample rate) µg
  • In RPL's testing, this value is somewhat worse than quoted, while still good.
    • At 20 Hz we measure ±300 µg
    • At 200 Hz we measure ±800 µg
    • At 6400 Hz and 25.6kHz we measure ±300,000 µg
• Cross Axis Sensitivity (affect of force in one axis on output of another axis): 2%
