Calibration of the Total and Static Pressure Transducers in the DSTO Transonic Wind Tunnel

Abstract

The total and static pressure of the DSTO Transonic Wind Tunnel (TWT) are each measured by a Paroscientific Digiquartz(registered trademark) pressure transducer. As part of the on-going quality management system these transducers have been recalibrated by the National Measurement Institute according to the National Association of Testing Authorities (NATA) standards. From the results of the calibration, zero and span adjustment parameters are determined. These parameters are then applied to the calibration equations supplied by the original equipment manufacturer to correct for the pressure reading. As a result, the standard errors of the total and static pressure are reduced to 0.0027% and 0.0026% of the full-scale reading respectively.
