Selection and calibration of pressure transducers for low pressure measurement (0.001 psia) in the tunnel 9 high altitude side force test (WTR 1365)
Abstract
A study of potential methods for measuring extremely low pressures (0.001 psia) in the NSWC Hypervelocity Wind Tunnel No. 9 was undertaken. Candidate techniques were evaluated in terms of compatibility with wind tunnel models, accuracy, response time, and availability. A detailed calibration was performed on random Microswitch, Model 130 PC transducers to check linearity, hysteresis, sensitivity, and repeatability. The effect of tube length and diameter on the response time of a pressure measuring system was also considered.
