NEW GENERATION 32bit SeedLink DIGITIZERS/RECORDERS

New generation “state of the art” 32-bit ADC seedlink digitizers / recorders, designed on our latest technology. They support three or six analog channels, ultra high resolution, especially in higher sampling rates from 250 to 1000 samples per second (sps). The effective resolution is 23.7 bits at 250 samples per second data rate, therefore they providing dynamic range greater of 138db. The effective resolution is even greater at lower sampling rates, and and it becomes close to 32bits when sampling rate is low like 10sps.(Delta-Sigma technology)

The instruments are based on a latest technology 32bit ARM type processor. The hardware is totally customized and there is no use of any third party hardware boards.

Total power consumption is very low, only 0.6W allowing the instruments to be in operation for long period, powered from a small 7.2Ah Lead-Acid battery. Timing is provided from a very accurate DPLL (digital pll) unit getting synchronized from a GPS receiver. The drift is extremely low (4*10-9sec) when GPS is off, but it periodically switched on (programmable) and synchronizes the DPLL. The digitizer provides also real time data streaming in parallel with local (microSD) data storage, trough the serial port, or Ethernet port. SRi32S unit model supports intergrated SeedLink server.

The seedlink digitizer provides also four extra analog lines, and four digital control lines, which may be used for seismometer control, mass monitoring etc.

The seedlink digitizer / recorder are ideal for micro-cracking monitoring, hydraulic fracturing monitoring, micro-seismic monitoring and other applications that high resolution and high dynamic range is required. Additionally broad-band seismometers like the STS-2 match perfect with the instrument because of high resolution provided.
