  • Agecodagis
  • CNSN
  • DAQSystems

    Below is some model-specific information to help you locate your instrument response. DAQ Systems have are four models: the 4, 4CH and 5V versions of the DAQ24USB use the CS5532 ADC chip, and the XR uses the ADS1255 chip.
    FIR filters are the same for dataloggers using the CS5532 chip, but sensitivities vary.
    The 4CH and 5V dataloggers have a Low and High sensitivity mode. Sensitivities are as follows: - 4.194310^5 Counts/V for the DAQ24USB-4, and the DAQ24USB-4CH and DAQ24USB5V at Low sensitivity - 2.79620310^6 Counts/V for the DAQ24USB-4CH at High sensitivity - 2.843596*10^6 Counts/V for the DAQ24USB-5V at High sensitivity

    Centaur

    Centaur digitizer technology is used within the Centaur standalone dataloggers, as well as all-in-one instruments such as the TitanSMA, TitanEA, MeridianCompact and MeridianPosthole. They use the same FIR filters, but offer different input (full-scale) voltage range options.

    CentaurHighGain

    The High Gain Centaur models have gains 4 times that of standard Centaur models.

They use the same FIR filters, but offer different input (full-scale) voltage range options.

The user may select the maximum full scale measurement range of +/-4g, +/-2g, +/-1g, +/0.5g +/-0.25g or +/-0.125g. This is applied to the internal Titan sensor, and so the Titan sensor response corresponding to the selected clip level should be used in conjunction with one of the digitizer responses below.

    TitanSMA

    The dataloggers in the Titan SMA and Titan EA digital accelerometers are Centaur dataloggers with a single preamp gain choice of 1 (40 Vpp). The user may select the maximum full scale measurement range of +/-4g, +/-2g, +/-1g, +/0.5g +/-0.25g or +/-0.125g.
