MOTUS 32-3
High Resolution Seismic Digitizer
MOTUS 32-3 is an all-in-one 3-channel high resolution (32bit) low noise digitizer with selectable gain, embedded computing, communication modules, GPS receiver that synchronize a high accuracy RTC and IP68 environmental protection especially designed to meet the harsh field conditions of several seismic related applications.
The digitizer has an external USB adaptor for data retrieval in the field and an internal USB module; data are stored in both devices for redundancy in order to eliminate the possibility of losing valuable data. There are several built-in communication module options and an Ethernet port as well for possible additional external communication options. A night readable LCD screen along with 4 control buttons enable the user to see the digitizer status and perform control functionalities as well, in the field without the need of an additional external control equipment (laptop or PDA). There is though a web interface for remote and local setup, command and control.
The embedded Computing module with linux OS host a seedlink server to enable real-time data acquisition and telemetry. Miniseed data are stored in both USB devices for local archive.
