  Wireless seismic data logger module   NordLab   NDAS-8224

 

NEW !

 

A 4-channels seismic data logger module is designed for battery-powered autonomous data acquisition systems including submerged seismic stations. The module has extremely low power consumption in operation mode - less than 300 mW. It is fully optimized for working with MTSS-2003 three component seismic sensor and СМЕ4211/4311OBS low power ocean-bottom seismometers.

The data transfer and system configuring can be carried out either via wired USB or wireless Wi-Fi connection, while 32 GB of onboard NVRAM allows for a long-term autonomous recording. The data logger is fully operational while powered from a USB port.

The wireless link makes it possible to set up the system as well as to perform the quality analysis of the data being registered remotely without any interruption to 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.

  Wireless seismic data logger   NordLab   NDAS-8226

 

NEW !

 

A 6-channels seismic data logger equipped with wireless interface Wi-Fi. Its excellent power efficiency and full compatibility with R-sensors' sensors family make NDAS-8226 the best choice for a long-term autonomous data acquisition.

The data transfer and system configuring can be carried out either via wired USB or wireless Wi-Fi connection, while 32 GB of onboard NVRAM allows for a long-term autonomous recording. The data logger is fully operational when powered from a USB port (in 500 mA mode).

The high-precision quartz generator which is locked-in to a GPS/GLONASS receiver gives the synchronization accuracy better than 1 usec. The deployment of the GLONASS makes better positioning reliability in high-latitude areas.

The wireless link makes it possible to set up the system as well as to perform the quality analysis of the data being registered remotely without any interruption to the system. The data logger is equipped with a stabilized power source for powering the seismic sensors and is also able to supply test signals such as various frequency sinus or 1 second length pulse for checking the attached sensors.

  Digital seismic station   Baykal / CME

This high-performance digital seismic station is based on broadband seismometers CME-4X11/ CME-6X11 and the self-contained seismic digital recorders Baykal-8. The high-resolution, wide dynamic range and perfect field operation applicability are the features of the seismic stations. The GPS is used for timing and positioning. The power supply is an expernal DC source (e.g. 12V-accumulator).

A seismic station optionally can be supplied with 3-component seismic accelerometers MTSS-1033A or MTSS-1043A for the strong motion measurements.

The seismic station is well suited both for permanent installation is seismic observatory and field applications. For the field application the station can be optionally supplied with the rugged case for transportation of digital recorder and accumulator.
