Titan Strong Motion Accelerometer

• Summary
  The Titan is a force balance triaxial accelerometer providing exceptional performance over a wide frequency range from DC to 430Hz.
  
  The Titan is engineered for high precision free field strong motion and structural monitoring applications requiring exceptional dynamic range combined with ultra-low self-noise performance comparable to many broadband seismometers.
  
  The Titan is the first accelerometer to incorporate digitally selectable full scale range and offset zeroing capabilities. The Titan is ideal for applications where the instruments are difficult to access or where frequent site visits are undesireable.
  
• Benefits
  • Exceptional performance with industry leading 166dB dynamic range
  • Ultra-low self-noise comparable to many broadband seismometers
  • Wide operational frequency range: DC to 430Hz
  • Electronically selectable full range for deployments in remote or difficult to access locations
  • High accuracy and low thermal drift provide increased data quality in structural monitoring applications
  • Integrated web server facilitates instrument management and control
