[en] A series of hydrogen:air combustion tests were performed at the Fully Instrumented Test Site (FITS), located at Sandia National Laboratories in Albuquerque, New Mexico, to evaluate the performance of three strain-gage-type pressure transducers in a combustion environment. The three types of gages were: Precise sensor models 111-1 and 141-1 and Kulite model XT-190. The evaluation was required since these three types of pressure transducers had been used in previous combustion test series at the FITS facility and the results were inconsistent. During this evaluation testing, Brunswick 1101 stainless steel felt metal was used to provide thermal protection for the transducer diaphragms. The objective of this work was to determine experimentally whether such shielding alters the dynamic pressure response of a transducer during a combustion experiment. Results of the sixty tests indicated that the three pressure transducers, when thermally shielded with felt metal, recorded peak combustion pressures that were generally within 5% of the statistical mean for each test
