Each wind tunnel is supplied with an NIST traceable certificate.\u003cbr\u003e \u003cbr\u003e The uniform flowrate is determined by monitoring a highly repeatable differential pressure sensor which has been calibrated to each individual wind tunnel as a system. Each wind tunnel is supplied with two restrictive plates for achieving optimum low flowrates. The established differential pressure measurements versus flowrates are listed from 25 to 9000 FPM. Calibration sheets are included, which makes calibrating different flow sensors simple.\u003cbr\u003e \u003cbr\u003e The differential pressure measurement used to establish known flowrates will be affected by barometric pressure and temperature conditions during testing. Depending on the probe being calibrated, humidity may also be a factor.\u003cbr\u003e \u003cbr\u003e OMEGA’s enhanced wind tunnel package is an environmental monitoring system that measures barometric pressure, room temperature, humidity and differential pressure.

The wind tunnels can be used to characterize different heat sink sizes for natural and forced convection cooling. Two heat sinks can be tested side by side to determine their thermal performance in the same environment. Actual or simulated PCBs can be tested for thermal flow distribution and pressure drop characterization. The WT-3106 and WT-3107 produce uniform air flows of up to 6 m\/s (1200 ft\/min). Air is drawn into the tunnel with up to 5 variable DC fans mounted at the exhaust section of the tunnel. These fans are mounted on a tray and can be easily replaced with another tray to accommodate larger or smaller fans. An internal flow management system, with honeycombs and screens, breaks up turbulence and provides uniform and homogeneous flow in the test section. The WT-3106 and WT-3107 can be operated both vertically and horizontally and features a Plexiglas® test section for ease of flow visualization. Rail guides are provided so the unit position can be adjusted. The WT-3106 and WT-3107 include 18 sensor ports in front and on the sides of the test section for inserting a variety of probes, such as thermocouples, pitot tubes, velocity measuring sensors, etc. The flexibility of the movable plate and housing provides users with a high degree of latitude to design and build their own setup to suit their needs.
