Seismic data logger module NDAS-8224
The NDAS-8224 seismic data logger module is designed for battery-powered autonomous data acquisition systems including land and ocean-bottom equipment.
The module has an extremely low power consumption in the operation mode that is less than 300 mW. It is optimized for operating with the MTSS-2003 three-component active geophone and СМЕ-4211/4311-OBS low power ocean-bottom seismometers.
The data transfer and system configuration can be carried out via wired USB or wireless Wi-Fi connection while 32 GB of onboard NVRAM allows for a long-term autonomous recording. The module is fully operational while powered from a USB port.
The wireless connection makes it possible to remotely set up the system as well as to perform the quality analysis of the data being registered without interrupting the system. The data logger is able to emit test signals such as various frequency sinus or 1-second length pulse and has an additional ±2.5 V DC power source for powering hydrophones.
