TITANACCELEROMETERWhat happens when the best class-A
accelerometer in the world meets the world’s most popular seisThe Titan is a force balance triaxial accelerometer that provides exceptional
mometer?
performance over a wide frequency range from DC to 430 Hz and featuresindustry leading dynamic range and ultra-low self-noise performance that iscomparable to that of some broadband seismometers.
As the first accelerometer to incorporate digitally selectable full scale range andoffset zeroing capabilities; the Titan's features are ideal for difficult to accessor remote deployments, where site visits should be minimized. The triaxial
sensor and electronics are housed in a rugged, compact aluminum enclosure
featuring a single bolt anchoring slot, adjustable leveling screws and integrated
bubble level.
Industry Leading Performance Attributes:• Industry leading 166 dB dynamic range• Ultra-low self-noise comparable to some broadband seismometers• Wide operational frequency range: DC to 430 Hz• Best in class thermal stability and high accuracy provide increased

Combine the Titan with theCentaur digitizer to achieve acomplete data acquisition andrecording system that is suitablefor deployment in both remoteand networked locations.

data quality• Full scale range of ±0.25 g to ±4 g with independent horizontal andvertical range selection
Ease of use advantages:• Electronically selectable full scale range facilitates remote sensor control
when deployments are distant or difficult to access• Integrated web server provides efficient instrument management
and control• Installation features that include an integrated bubble level, adjustableleveling screws, single bolt keyhole mount, and a compact footprint ensurethat deployments are completed efficiently and quickly
