Abstract
A method for detecting the blocking of a drain hole of a pressure measurement probe by means of an acoustic checking device, the probe comprising an internal volume provided with at least one drain hole communicating with the outside of the volume, the checking device being able to be connected to the internal volume of the probe and comprising means for measuring an acoustic imprint of the internal volume. The method comprises: measuring an acoustic imprint by plugging the at least one drain hole from the outside of the volume; measuring an acoustic imprint without plugging the at least one drain hole from the outside of the volume; and comparing the two measured acoustic imprints.
