Frequently Asked Questions (FAQ)

• What signal output does this accelerometer use?
  The CA901 provides a charge output and requires a compatible charge converter for signal processing.
• Can I use this sensor in a hazardous location?
  Yes, it holds the LCIE 08 ATEX 6017 X certificate for use in explosive atmospheres (Zones 0, 1, 2).
• What is the transverse sensitivity of the device?
  The transverse sensitivity is typically less than 5% of the main axis sensitivity.
• How do I determine the lower frequency cutoff?
  The lower cutoff frequency of 3 Hz depends on the external charge converter electronics you use.
