Code: B209-16

The CDAS2 Control and Data Acquisition System from Pavetest is a compact, high-performance solution for real-time control and data acquisition in pavement testing. Designed for ultimate versatility, the CDAS2 supports up to 16 channels with 24-bit resolution and sampling rates of up to 200,000 samples per second simultaneously on all channels, ensuring exceptional waveform fidelity for the most demanding laboratory and research applications.

The system includes TestLab software supplied on a USB flash drive, with pre-loaded method and calibration files for all transducers provided. Methods and software can be expanded to accommodate future testing requirements.

Compact and lightweight, the CDAS2 combines high-speed acquisition with robust control, making it ideal for research, quality control, and advanced testing of asphalt and pavement materials.

16 Channel CDAS2 - Acquisition 16 CH, 24-bit resolution

  • Sampling rate up to 200 kHz (all channels)
  • Smoothing up to 64 times over-sampling
  • Calibration automatically on power up
  • Control Axis 4
  • Communication: USB or Ethernet
  • Directly communicates with the TestLab software, providing automatic test execution and data processing.
  • Compact high-reliability data acquisition and control.
  • Up to 5 kHz data acquisition and feedback control provide excellent waveform fidelity.
  • Up to 64 times oversampling gives superior low-noise performance.
  • Normalised (±10 V) analogue data acquisition inputs provide flexibility to use any transducer in any channel.
  • Automatic recognition of transducers and upload of calibration files.

CONTROL:

  • Up to 6 high-speed (18-bit) digital servo-control axes.
  • Digital closed-loop update sampling rate of 5 kHz per axis.
  • Computer programmable, Proportional, Integral and Derivative (PID) control algorithm.
  • Adaptive Level Control (ALC) algorithm for best dynamic peak accuracy.
  • 3 feedback control modes. e.g., force, position and on-specimen strain.
  • “Bumpless transfer” between control modes.

ACQUISITION:

  • Analogue inputs are automatically calibrated on power up.
  • Simultaneous sampling of all channels.
  • Up to 24 analogue (± 10 Volt) input channels.
  • Up to 64 times oversampling (set to 8 by default).
  • 24-bit digital resolution (approx. 1/16,777,216), no auto-ranging required.
  • Sampling rate up to 200.000 Hz.
