  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.

  High-performance seismic digital recorder   Baykal-8 v.3  (BY-8)

 

Renewed in 2016

 

The mobile high-resolution seismic signal recorder "Baikal-8" is the autonomous seismic station which can be used to record external seismic or other sensors signals in wide frequency band with high accuracy and synchronization with UTC.

The device can be used for operational and long-term seismic and geophysical measurements in real field conditions in a wide range of temperatures. Large nonvolatile (NVRAM) memory volume, built-in high-stability generator and a GPS module, high-quality analog-digital tract provide excellent operational characteristic for solving a wide class of problems.

Ethernet support allows to use the standard solutions for connecting several devices into the network. Wireless data transmission can be achieved using wireless-ethernet routers. FTP and SeedLink support makes possible to use the standard software for remote data retrieval. Standart file system and MiniSEED format are supported.

  Self-contained seismic digital recorder   Baykal-7HR / Baykal-7A    This model is discontinued!

This high-performance self-contained 3-channel seismic digital recorder has the high-resolution Σ-Δ analog-to-digital converter, stabilized temperature-compensated generator, reliable reverse-voltage and short circuit protection and built-in (or external) GPS-receiver with 5m GPS antenn cable.

The device can be supplied with the remote (up to 200m) GPS-receiver that alows it's stable operation in enclosed spaces (such as vault etc.).

Applications: self-contained portable seismic and geophysical data acquisition systems.

Equipped with included data download management software, data analysis and processing software.

Version Baykal-7A is similar to Baykal-7HR excepting different types of analogue and power connectors.
