Controller Automates Wind Tunnel Testing
September 7, 2005 |Estimated reading time: Less than a minute
NORWOOD, Mass. — WTC-100 from Advanced Thermal Solutions, Inc. (ATS) is a fully automatic controller for laboratory wind tunnels that are used to thermally characterize PCB components, heat sinks and card racks. Two independent sensors simultaneously measure air velocity and temperature to provide a wide range of wind-tunnel test conditions. It regulates air velocities from 60 to 10,000'/min, and rapid feedback from the sensors maintains the air flow in the test domain to within ±0.5% of the set velocity. It operates on all PC platforms with ATS' stageCONTROL software, which is a labVIEW-based application. The stageCONTROL program allows users to precisely set the air flow range, including flow ramping and dwell times from minimum to maximum points. It provides an interface for wind tunnel calibration and for setting up and conducting thermal characterization tests. WTC-100 reportedly can measure device temperatures from -10° to 150°C. A basic WTC-100 unit can power up to 24 VDC fans, and different voltage fans can be used upon request. The controller measures 10.40 × 13.8 × 4.5".
