The unit has an integral liquid crystal display with a scroll switchthat allows all 32 channels to be viewed in groups of four at any time. Theconditioned outputs of the pressure sensors, and any other connected compatibleelectronic instruments, may be output to Versatile Data Acquisition System toallow computer based data acquisition and display. The 32-Way Pressure Display Unit is an optional ancillary tomodular Subsonic Wind Tunnels. The unit mounts onto the control and instrumentationframe of the wind tunnels. Connection to each of the 32 calibrated pressuretransducers is via quick-release pressure inputs mounted on the front panel ofthe unit. It measures and displays up to 32 pressures frommodels, Pitot-static tubes and other measuring instruments fitted to a windtunnel. It is ideally suited to applications where multiple pressuremeasurements are required, for example in boundary layer and tapped aerofoilmodel investigations. This allows easy and quick connection between the unit and anexperiment mounted in a wind tunnel. When the 32- Way Pressure DisplayUnit is used with the system it allows laboratory time to be used more efficientlybecause data can be captured and processed much more quickly than when usingmanual techniques. All pressures are measured with respect toatmosphere. Using enables accuratereal-time data capture, monitoring, display, calculation and charting of allrelevant parameters on a suitable computer. This option providessignificant experimental advantages over conventional instruments such asmanometers. The facility in the software to average data to remove thefluctuations inherent in wind tunnel measurements enhances the quality of theresults by making their interpretation much easier.
