Fan Performance Testing with °C SPAR

November 14, 2022 | Posted By: Degree Controls Inc.

Do you need to test fan airflow?

The °C SPAR is a fully configurable Sensor Pole Array system for linear air velocity, temperature, and humidity measurement. Manufacturers, product testing labs, and engineers involved in the development and design of test equipment use °C SPARs to measure fan performance. It is an efficient and effective tool to measure multiple points of air velocity simultaneously.

°C SPAR sensor arrays are built to user defined dimensions including pole dimensions, velocity calibration ranges, and sensor quantities to meet distinct airflow application requirements. The °C SPAR is a versatile instrument. It can accommodate an array of designs, including portable grids, multi-tiered racks, and perpendicular and radial arrangements. Prevalent in test equipment for fan performance testing and evaluations, perpendicular °C SPAR arrangements can be structured to accommodate small-diameter and large-diameter fans.

°C SPAR systems record airflow, temperature, and humidity in real time. Calibrated flow ranges are available from 0.15 to 20 m/s, and °C SPAR is capable of measuring with ± 3% accuracy. The sensor pole arrays terminate with convenient USB connectors to plug directly into °C Port data acquisition instruments. Combined with AccuTrac™ data logging software, up to 180 airflow measurements can be viewed and analyzed in real time on a laptop or PC. Test data is saved and shared in universal csv and png formats.

Versatility, plug and play connectivity, and the multipoint measurement feature of °C SPAR systems make it an unparalleled tool for airflow testing and evaluation. °C SPAR offers significant time savings as compared to a single point measurement approach.

Fan performance testing is not the only place you will see °C SPARs in use. They are used by HVAC professionals for duct traversing to get an average air velocity, and by certifiers for grid-based measurements of face velocity and downflow velocity in a single setup.
