USB Data Acquisition Systems

What is a USB Data Acquisition System:

USB is the favored interface for a range of portable applications including industrial condition monitoring, vibration & acoustic test rigs. The main benefits for this are that many IEPE sensors require low voltage. USB Cables provide enough power for both the unit and any attached sensors, which means no external power supply is needed. When the device is plugged into PCs using the Windows Operating System hardware is automatically detected then configured this Plug and Play [PnP] compatibility makes them very easy to use. USB equipment tends to be much cheaper than Data Loggers, Wireless or Ethernet devices, USB 2.0 is reasonably fast; ensuring maximum throughput.

4-channel dynamic data acquisition units are used for making accurate measurements from a variety of sensors, including tri-axial accelerometers, displacement transducers and microphones. Connecting through Hi-Speed USB, each signal is memorized, filtered & then sampled, in real-time, by a 24-bit Delta-Sigma digital Anti-aliasing ADC device. This aids in discriminating between signals providing an accurate recording of desired signals while, based on the frequency range or bandwidth, unwanted signals are discarded.
