Minimus - A revolution in miniature!
Minimus digitisers offer advanced 'smart' 24-bit seismic ADC conversion and are packed with a host of features that make them the ideal 'plug-and-play' solution for rapid deployments and multi-scale networked arrays.
For Earthquake Early Warning applications, features include industry standard triggering algorithms (STA/LTA); multi-instrument voting to mitigate false positive alerts; Common Alert Protocol (CAP) for automated emergency warning; plus an ultra-low-latency mode which when used with our GDI protocol means network transmission can be achieved in 40 milli-seconds (network dependent).
Available in 4-channel (Minimus and Minimus2) or 8-channel versions (Minimus+).
Minimus is also available as an OBS module for ocean floor deployments. You can read more about this on page 17 of our Ocean Bottom Seismometers brochure.
The four channel Minimus can simultaneously accommodate a triaxial analogue sensor, an auxillary input e.g. for infrasound; a Radian posthole or borehole instrument; plus its own internal MEMS accelerometer (2g)
