The NI FieldDAQ series comprises high-performance data acquisition systems (DAQ) that have been specially developed for extreme environmental conditions. These devices enable precise measurements directly at the sensor source, even under extreme temperatures, vibrations or humidity. Thanks to the protection classes IP65/IP67 and their robust design, they are ideally suited for outdoor use and harsh conditions.

Typical areas of application include:

  • Environmental and structural tests
  • HALT tests (Highly Accelerated Life Test)
  • NVH analyses (Noise, Vibration, Harshness)
  • Tests of rocket engines and flight structures
  • Field tests on off-road vehicles
  • Academic research (e.g. wind tunnel and climate tests). Academic research (e.g. wind tunnel and climate chamber measurements)

With support for different sensor types (voltage, temperature, IEPE, strain measurement) and compatibility with NI FlexLogger™, LabVIEW, Python and C/C++, FieldDAQ offers a flexible and powerful solution for modern measurement systems.

Features and differences:

The FD-11637 is specially designed for strain measurements with bridge circuits. It supports quarter, half and full bridges as well as various excitation voltages and is therefore ideal for mechanical testing, structural testing and fatigue analysis.

Differences to other variants:

  • FD-11601: Voltage input (±10 V) with sensor supply
  • FD-11614: Thermocouple measurements (16 channels for temperature data)
  • FD-11634: IEPE inputs for sound and vibration measurements
