ATLAS

Atlas is a digital recorder designed for structural and seismic monitoring applications, whenever a robust and reliable “stand-alone” instrument is needed to continuously record data over a long period of time.
The system is available with 3, 6 or 9 differential input channels for external sensors.

EXCELLENT PERFORMANCE

The instrument is equipped with high-resolution delta-sigma 24bit ADCs, all the channels are synchronized and the sample rate is adjustable up to 1000 sps per channel. The internal memory (up to 1TByte) has two independent recording zones: the ring-buffer zone which is dedicated to continuous sampling, and the triggering zone which is used for event sampling.

The data format is MiniSEED.

The built-in GNSS receiver synchronizes the system clock with the absolute time so that a network of several units can be created where all the channels are synchronized. Using the trigger criteria that is available in the firmware, it is possible to distinguish environmental vibrations from seismic events.

EASY TO USE

You can control Atlas locally via network connection (LAN or WiFi), and remotely using the integrated 4G modem (optional). The instrument can be used as a “stand-alone” unit to record seismic events in the field or it can be used in a MASTER-SLAVE based monitoring network where multiple instruments are connected to each other; the MASTER device manages the interconnection with the other SLAVE units, collecting data from them and managing the connection with the remote server. Furthermore, MASTER and SLAVE units can perform periodic analysis of ambient noise and post-seismic vibrations in order to evaluate the structural damage caused by an earthquake, in real-time.

Thanks to SeedLink protocol Atlas is compatible with most popular seismic analysis software (Seiscomp3, Antelope, Earthworm).

INTEGRATED UPS

Atlas is equipped with an internal battery (LiPo) which can guarantee an autonomy of about 33 hours in case of a blackout. This feature is greatly appreciated by our customers because it is like having an integrated UPS, and it saves space and money; both the 4G modem and external sensors’ power supply is backed up by the internal battery. Atlas’ power supply ranges from 9 to 28VDC, it can be connected to the electric power network with the power supply adapter included.

ROBUST

The anodized aluminum (INOX AISI316 option) enclosure is CNC milled, shockproof, vibration-resistant, weather-resistant and designed with a built-in mounting brackets for easy installation.
