City Shark II - Ambient Vibration Recorder

City Shark II is a reliable versatile Data Acquisition System dedicated to geophysical and civil applications.

This synchronous multi-channel (uo to 18) recording device mainly designed for ambient vibration recording is able to record any low voltage signal.

City Shark II is a user friendly compact portable tool efficient for soil and building dynamic parameters studies.

The internal GPS, high quality clock and continuous recording capabilities allow City Shark II to be used also for Earthquake Monitoring.

City Shark II Applications:

    • Ambient Vibration Studies - Single Station or Array

    • Civil Engineering Investigation

    • Earthquake Monitoring

    • Geophysical Research

Benefits and Advantages in using City Shark II

City Shark II is an independent portable device with a powerful internal battery, a removable compact flash card for efficient data storage for synchronous recording of one to six 3-component sensors (3 to 18 channels).

Recording parameters are set-up through push buttons, no need to use an external device.

Both passive and active sensors may be used. Active sensors are directly powered by the station itself through the same cable as the recorded signal.

Internal noise is so low that it allows using a 4.h Hz sensor to study frequencies down to as low as 0.2 Hz.

Other City Shark II advantages are:

  • Flexibility

  • Portability

  • Accuracy

  • Large Storage Capacity

  • Extractable Compact Flash Card

  • Low Voltage Battery Detection

  • Internal GPS

  • Continuous recording mode with selectable data storage size (1 to 60 min)

  • Possibility to connect to an external battery
