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 accelerometric 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 24 bit ADCs, each channel is 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.
Using trigger criteria available in the firmware, it is possible to distinguish environmental vibrations from true seismic events.
The built-in GNSS receiver synchronizes the system clock with the absolute time so a network of several units where all channels are synchronized can be created.
You can control Triton Accelerograph locally via network connection (LAN or WiFi), and remotely using the optionally integrated 4G modem.
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 coming from them and managing connection with the remote server. Furthermore, MASTER and SLAVE units can perform periodic analysis of the 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 is compatible with most popular seismic analysis software (Seiscomp3, Antelope, Earthworm).
Triton’s power supply ranges from 9 to 28VDC, 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 optional) enclosure is CNC milled, shockproof, vibration-resistant and weather-resistant, it is optionally equipped with a fixing plate or spikes for easy installation.
