Atlas-C is a variant of the Atlas digitizer. It was conceived as rugged version of the recorder, to be used in harsh environments.
The Atlas-C is light and portable, our customers appreciate its user-friendliness and high performance. Atlas-C is available with 3, 6 or 9 differential input channels for external sensors.
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 system 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.
Atlas-C comes with built-in (not removable) memory and a hot-swappable memory on the outside. Its firmware writes both memory banks redundantly. The user can eject the external card and interchange it while the recording is running without affecting the contents of the internal memory.
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. The dual auto-switching GNSS antenna feature, allows the user to use the internal antenna if the instrument is under a good sky view or to install an external antenna when needed.
The instrument can be controlled locally via network connection (LAN or WiFi), and remotely using the integrated 4G modem (optional). The SIM card is in micro format which is accessible to the user from the top panel. Both WiFi and 4G antennas are integrated in the instrument.
Thanks to the SeedLink protocol, Atlas is compatible with most popular seismic analysis software (Seiscomp3, Antelope, Earthworm).
The large capacity internal back up battery guarantees long term recording in the absence of an external power supply (typically 33hrs). This feature is greatly appreciated by customers because it is like having an integrated UPS, which saves space and money; both the 4G modem and the external sensors’ power supply is backed up by the internal battery.
The power supply ranges from 9 to 28VDC and it can be connected to the electric power network with the power supply adapter included.
Atlas-C can also be connected directly to a solar panel.
Atlas-C comes in a plastic case with a transportation handle. The enclosure is shockproof, vibration-resistant and weather-resistant IP67.
