USB Data Acquisition Systems

USB devices are the preferred interface in a range of portable applications such as industrial condition monitoring, vibration & acoustic test rigs. The primary reasons for this are that many IEPE sensors require low voltage. The USB Cable is enough to power both the unit and attached sensors; in most cases no external power supply is required. PnP [Plug and Play] Compatibility, when the device is plugged-in to PCs using the Windows™ OS the hardware is automatically detected and configured making them easy to use. USB units don’t cost as much as Data Loggers or Ethernet devices, the speed of USB 2.0 ensures maximum throughput.
4-channel dynamic data acquisition units are used for making accurate measurements from a variety of sensors, including tri-axial accelerometers and microphones. Connecting through Hi-Speed USB, guarantees data throughput, each signal is recorded, filtered & sampled by an in-built 24-bit Delta-Sigma digital Anti-aliasing ADC device. This adjusts to discriminate between signals providing an accurate recording of desired signals while, based on the frequency range or bandwidth, discarding unwanted signals.

Some typical features of a USB Data Acquisition System:
•    4 channel; 24-bit resolution
•    Continuous; synchronised acquisition
•    100kHz per channel
•    USB2.0 interface
•    Selectable input signals such as voltage and ICPE
•    Easy configuration
