SENTINEL-X is a budget-friendly premium-quality 4-channel digitizer designed for strong-motion and geophysical monitoring.
The analog channels are 40 Vpp capable and synchronously sampled up to 500
samples/second at a resolution of 24 bit. Dynamic range exceeds
125 dB@100 Hz.
The integrated memory bank (32 ÷ 256 GB) allows you to manage a ring-buffer for continuous long term recordings as well as event data. The data is saved in MiniSEED format.
The system implements sophisticated trigger criteria (STA/LTA and threshold) which distinguishes false events (i.e. environment vibrations) from true seismic events.
The internal GNSS receiver allows you to create a network where all the instruments are synchronized to the absolute time.
The connection to the instrument can be established either using the local network
(LAN or WiFi) or, alternatively, remotely using the optional internal HSPA (4G
The instrument can be used as a stand-alone unit, or in a MASTER-SLAVE based monitoring network where multiple instruments are connected to each other; Sentinel-X is compatible with both the Triton and Atlas, which is useful when superior dynamics are needed, for example, as a near field monitoring system.
Thanks to the SeedLink protocol, SENTINEL-X is compatible with the most popular seismic analysis software: Seiscomp3, Seiscomp4, Antelope and Earthworm.

SENTINEL-X is powered by an external DC source (5 ÷ 16 Volt DC) and it is equipped with
its own internal battery (LiPo), which can guarantee an autonomy of 5 hours in case
of a blackout. The battery is a standard 18650 and can easily be replaced. The
HSPA modem (optional) is backed up by the internal battery.
Input connectors are provided with a battery back-up 12V@50mA power supply that can be used for powering the connected sensors.
SENTINEL-X comes in an anodized aluminum case which is rugged and shock-resistant and therefore well suited to field use. Sensor connectors are industry standard M8, robust, and easy to find on the market.
