LabVIEW Hardware for Data Acquisition etc

These days, computers can be connected to almost anything via data acquisition devices and other interfacing hardware. LabVIEW provides the means for communication to take place.

What is LabVIEW Data Acquisition?

“Data acquisition” in a LabVIEW-based system can include one or more of the following:

  • Signal conditioning
  • Measurement of voltage, current, temperature, pressure etc
  • Counting and timing of pulses
  • Digital I/O and switching
  • Signal and pulse generation

Data Acquisition Devices

To achieve these things we have become experienced in using equipment from National Instruments including:

  • CompactDAQ
  • Data acquisition cards such as E- and M-Series
  • FieldPoint and Compact FieldPoint
  • CompactRIO
  • PXI
  • SCXI
  • R-series cards (FPGA)

Motion Control Devices

We have used stepper and servomotors together with motion controllers from companies like National Instruments, Aerotech, Lenze and Danfoss.

Vision Equipment

We have completed several projects that included image acquisition from one or more cameras. Some of these have included image processing and pattern recognition. We have used vision equipment from companies like National Instruments, Pleora, Axis Communications and Kodak.

Communication Buses for Other Devices

For a PC to communicate with any device, a communication bus is typically required. We have experience of using such buses to communicate with:

  • Temperature controllers
  • PLCs
  • Power supplies
  • Weigh scales
  • Oscilloscopes
  • Lasers
  • A refractometer
  • Mass spectrometers
  • Ultrasonic probes
  • And many other devices.

Buses we have used to communicate with these devices include:

  • RS232
  • RS485
  • Modbus
  • USB
  • Ethernet
  • CAN
  • GPIB

Each of these buses has its own idiosyncrasies. CAN and GPIB require cards which are available from National Instruments. Multiport serial cards are also available and bus converters are sometimes useful – such as USB to RS232 converters.
