miniLDV G5

Reliable. Portable. Precise.

Data collection made simple. Ideal for industrial and research applications, the miniLDV G5 is a pencil length sensor that sets up in under 30 minutes. Proprietary technology enables a miniaturized and rugged sensor at a fraction of the traditional LDV size. A wide range of customizations will meet any experimental demands. Permanently aligned and calibrated, results can be acquired quickly, even with no previous experience. Just plug it into a computer, point it at the target, and it’s ready to perform. For fluids research, surface speed measurements, wind tunnel analysis, and more, the miniLDV G5 is the versatile sensor solution.

Advantages of the miniLDV G5

Compact and lightweight
No alignment or calibration required
NIST traceable calibration offered
Velocity Range from low to supersonic
Frequency shifting feature measures flow direction along with speed

The miniLDV System consists of the miniLDV probe, Processing Engine and the 1D Burst Processor Acquisition Manager software package. Optionally available are linear traversing systems (one or two axes) with manual or electronic drive (electronic traverses are controlled from within the software) and a computer with the software installed and verified by MSE technicians. The miniLDV probe is also available with an integrated Processing Engine as the Integrated miniLDV.

*These distances are measured in air. When aimed into an experimental vessel with a different fluid, the probe volume will be farther from the probe and it will be slightly larger. Please refer to the specifications at left for examples.
