The Differential Pressure Transducer and readout is an optionalancillary to Subsonic Wind Tunnel. It measures and displays pressures inPitot-static tubes and other pressure-sensing devices fitted to a wind tunnel,with respect to the atmosphere or differential pressures. The control andinstrumentation panel of the wind tunnel includes a location for mounting up totwo Differential Pressure Transducer modules. It is microprocessor-controlledand contains a calibrated pressure transducer. The unit has an integral liquidcrystal display that allows the user to read pressure directly. The signals ofthe pressure sensors may be output to optional Versatile Data AcquisitionSystem. Using enables accurate real-time data capture, monitoring, display,calculation and charting of all relevant parameters on a suitable computer.When the Differential Pressure Transducer is used with the automatic dataacquisition unit it provides a significant advantage over conventionalinstruments such as manometers. Many readings can be taken and the user may usea suitable spreadsheet software package to obtain a more accurate overview ofpressure distributions.
