  • State-of-the-Art ADC
  • Watertight Integrity IP68
  • Embedded/Removable Mass Storage
  • IP Communications over Ethernet and Asynchronous Serial

Modular Hardware and Software

REF TEK 130S-01 Broadband Seismic Recorder digitizes and stores analog input from geophysical sensors. It’s compact, requires low-power, low-maintenance, and includes rapid event notification telemetry for ultra-low latency data transmission.

The 130S is constructed with up to five internal boards stacked together. This arrangement is more reliable and less costly than a traditional backplane arrangement. The 130S comes with a Lid Interconnect Board, a Microcomputer Board, one or two ADC Boards and a Sensor Control Board.

Remote command and control of the unit is available via software for iPhone (iOS 5.0 or later) or Windows (7 or later.) Additionally, State-Of-Health monitoring is accomplished with an extensive set of Status commands.

Aftershock & Microzonation Recorder

160-03

krohne ultrasonic flow meter
  • Self contained unit with integrated sensors
  • Three internal 2Hz Geophones
  • Internal triaxial MEMS accelerometer
  • Swappable, rechargeable batteries
  • No field set-up required

Seven Days Autonomy

The 160-03 is a self-contained, fully integrated Aftershock System providing simple and quick deployment during aftershock emergency mobilization. During deployment, the dedicated 160-03 app can connect to the unit via Wi-Fi to stream real-time data for all six channels.

The self-contained rechargeable battery pack provides power autonomy up to 7 days during continuous data acquisition at 200 sps on three recording channels. For longer power autonomy, the 160-03 Aftershock System battery pack can be charged from an external source.

Remote command & control of the unit is available via software for iPhone (iOS 5.0 or later) or Windows (7 or later.) Additionally, State-Of-Health monitoring is accomplished with an extensive set of Status commands.

Rapid Event Notification / Recorder

130-REN

krohne ultrasonic flow meter
  • RTP data transmission and rapid event notification
  • Outputs digital data every 0.2 seconds
  • 100% end-to-end error correction with backfill algorithm
  • Dual link data transmission for redundant central recording sites

Data Latency over LAN 0.4 sec.

Model 130-REN-3 has been specifically designed to meet the key requirements for Earthquake Early Warning Systems (EEWS) and Rapid Event Notification (REN) systems by quickly delivering digital data from the seismic station to the data processing center for the real-time earthquake notification system to provide a warning prior to significant ground shaking.

The 130-REN recorder allows output of digital data every 0.2 sec with 0.4 sec latency over LAN. The 130-REN uses a backfilling algorithm to keep track of data packets that have not been acknowledged and re-transmits those data packets.

The 130-REN allows you to meet the critical requirements of the Rapid Seismic Event Notification System by detecting strong ground shaking at one or several locations, and transmitting a warning notification ahead of the seismic energy affecting a populated area.

Strong Motion Accelerograph

Ref Tek Seismic Sensor
  • 24 Bit ADC
  • Low Noise
  • Low Power
  • Wide Dynamic Range
  • Simultaneous telemetry and local recording

REF TEK 130-SMHR

The 130-SMHR meets the USGS Advanced National Seismic System (ANSS) specifications for strong motion reference stations for deployment in urban areas and has an internal high resolution force-balance accelerometer with a dynamic range >155dB, and a high precision oscillator for precise time-keeping.

The 130-SMHR advanced communication features include TC/IP over Ethernet and asynchronous serial.Onboard LCD displays health and status information. Command/control interface allows the user to review and program the instrument’s operating parameters and perform diagnostic functions; acquisition status, sensor calibration, trigger parameters.

The instrument case size allows the installation of an internal battery to provide backup power for more than 48 hours.

130-MC Multi-Channel Accelerograph

The 130-MC is a robust multi-channel recorder designed for civil engineering and structural monitoring requirements. Built-in communication capabilities allow for real-time and on-demand data collection so that you can monitor your site and respond appropriately.

The 130-MC’s network capabilities allow multiple units be interconnected for more comprehensive coverage of movement in a building or on a structure such as a bridge or a dam.

Available in a 12 or 18 channel recording system with advanced telemetry for real-time data collection on all channels. The 130-MC is designed specifically to work with the REF TEK® 147A strong motion accelerometer, but has the flexibility to connect other sensors.

These units sense seismic motion.
