TRITON accelerograph is an integrated data acquisition system plus sensor which was conceived for applications where a combined and space-saving solution are required. Very low seismic noise levels are achieved thanks to the sensor being shielded inside the enclosure and to the short wiring.
TRITON accelerograph is available with MEMS or true mechanical Force Balance Accelerometer (FBA) sensor. Two different dynamic ranges are available for the MEMS sensor 90dB and 110dB, while the force balance sensor is 160dB.
The TRITON accelerograph can be equipped with extra inputs for 3 or 6 24-bit channels. In this configuration, in addition to the internal sensor, the instrument can be externally connected to two other high dynamic 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 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.
You can control TRITON accelerograph 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 TRITON accelerograph is compatible with most popular seismic analysis software (Seiscomp, Antelope, Earthworm).
TRITON’s power supply ranges from 9 to 28 Volt DC, it can be connected to the electric power network using the included power supply adapter. TRITON is equipped with an internal battery (LiPo) which can guarantee an autonomy of about 33 hours in the case of a blackout. This feature is greatly appreciated by our customers because it is like having an integrate UPS, and it saves space and money; both the 4G modem and the external sensors’ power supply is backed up by the internal battery.
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.
TRITON is designed to suit various applications and provide a solution to the users needs in the field.
Daisy Chain Daisy Chain connection is intended for all the applications where many devices are installed in-line and where guaranteeing enough sky-view for GNSS is difficult and there’s no local power supply.
Beneficting from the daisy chain connection, TRITONMASTER, which guarantees GNSS
coverage and power supply, will then synchronize and power-up all the installed
Thanks to the pass-through connection, each device can pass synchronization and power supply to the next one.
You can have TRITON configured according to your needs
