CR24bit Digitizer - The SR-24 seismic recorder

24 bit resolution digitizer / recorder Low Power consumption GPS / DPLL time accuracy. Sampling Rate 1 – 750sps Selectable input range +/-2Vpp to +/-40Vpp Continuous Recording Mode Removable CF data storage FAT16 or FAT32 filing system Operating Temp -20 to +70oC LCD screen Serial or Ethernet data & control port

The SR-24 has 3 input channels, and capability for connection to a wide range of sensors. The digitizer is based on a powerful, wide dynamic range delta-sigma analog-to-digital converter, with very low noise characteristics and excellent power supply rejection. The sampling rate can be set to 40, 50, 60, 100, 125, 150, 200, 250, 300, 400 and 500 samples per second. Optional, sampling rates of 1, 2, 5, 10, 20, 25 and 600, 700, 750,1000 samples per second can be supported. Data are stored in a Compact Flash type storage unit. Typical storage unit is 2 GB, enough to store approximately 26 days data of 3 channels @ 100 samples per second. Larger than 2GB Compact Flash Card Unit can be used to increase the recording period.

The power consumption is extremely low, allowing the recorder to operate for long time period connected to a typical 12V/55Ah battery without the need of recharging.Communication plug-in allows the instrument to be connected to any Seiscomp PC. Seiscomp server collects data from the remote stations.

The LCD display, displays the State-of-Health, time and date  and other information related to the instrument’s operation.

Software tools have been also developed to support both field and base station operation. The recorder is intended for installation in harsh environments and is supplied with a portable waterproof plastic case, manufactured of HPX high performance resin, with easy press & pull latches and durable soft-grip handle with easy access to all user features.
