Abstract
A device is provided for checking a probe for measuring the pressure of a flow, the probe comprising an internal volume and at least one orifice communicating with the outside of the volume. The device comprises: an acoustic transmitter and an acoustic receiver; connection means to connect the device to the probe, such that the transmitter transmits an acoustic signal propagated in the internal volume, and such that the receiver picks up an acoustic signal observed in the internal volume; processing means suitable for comparing the observed signal to a reference signal. The connection means are configured in such a way that an incorrect connection of the probe disturbs the propagation in the internal volume of an acoustic signal transmitted by the transmitter. The processing means are configured to detect an incorrect connection of the probe by comparing the acoustic signal observed in the internal volume with the reference signal.
