This low power digitaliser Seismic Recorder resolution 6+1 analog seismic channels telemetry digitiser/recorder. 32bits ADC converters provide effective resolution better than 23.7bits@100sps. The size of the instrument is only 168x106x68mm.
The power consumption is only 1.2W for 7 channels. Available sampling rate is 1 to 500sps/6ch, 1 to 1000sps/3ch and optional. 0.1 sps is supported. Buld-in GNSS receiver combined with ultra accurate DPLL unit providing time drift 10e-9 sec ensures timing stability even in the absence of GPS signal. NTP timing is also available.
The unit is very flexible and accepts several types of analog front end units so any type of seismic sensor can be connected.
Additionally, it provides eight extra low resolution and rate analog inputs for seismometer mass position monitoring, or any other environmental parameter monitoring.
Eight TTL command outputs are supported for seismometer control or for any other external device control. Typically, the digitiser supports differential variable gain preamplifier. Our force-balance sensor front end is also supported, providing a wide-band response (10sec-98Hz) and high sensitivity 1500V/m/s by connecting a C100 sensor.
Acquisition parameters and operation modes can be set from the user-friendly web interface, up to 64 characters
password protected. The unit operates in continuous mode, triggered mode or both and data are streamed through different data ports. Local data storage is selectable as well as logfile information.
