DIFFERENTIAL PRESSURE TRANSDUCER

The Differential Pressure Transducer and readout measures and displays pressures in Pitot static tubes and other pressure-sensing devices fitted to the AF1300 Subsonic Wind Tunnel, with respect to the atmosphere or differential pressures.

The control and instrumentation panel of the AF1300 wind tunnel includes a location for mounting up to two Differential Pressure Transducer modules. It is microprocessor-controlled and contains a calibrated pressure transducer. The unit has an integral liquid crystal display that allows the user to read pressure directly.

The signals of the pressure sensors may be output to TecQuipment’s optional Versatile Data Acquisition System (VDAS®, available separately). Using VDAS® enables accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer (computer not included).

When the Differential Pressure Transducer is used with the automatic data acquisition unit it provides a significant advantage over conventional instruments such as manometers. Many readings can be taken and the user may use a suitable spreadsheet software package to obtain a more accurate overview of pressure distributions.
