摘要

The invention relates to a device for monitoring a probe for measuring the pressure of a flow; the probe comprising an internal volume; the device comprising: an acoustic transmitter and receiver, connection means intended to connect the device to the probe, for the transmitter to transmit an acoustic signal in the internal volume and for the receiver to pick up an acoustic signal in the internal volume. The device also comprises an electronic module comprising: an audio transmission and reception circuit, linked to the transmitter and to the receiver by analog link, a non-erasable memory comprising a digital encryption key, an erasable read-only memory, a digital communication interface, configured to transmit or receive digital signals between the outside of the device and the audio circuit, the non-erasable memory and the erasable read-only memory.

1. A device for monitoring a probe for measuring the pressure of a flow; the probe comprising an internal volume and at least one orifice connected with the outside of the volume; the device comprising:
an acoustic transmitter and receiver, connection means intended to connect the device to the probe, so that the transmitter transmits an acoustic signal that is propagated in the internal volume and so that the receiver picks up an acoustic signal observed in the internal volume, an electronic module comprising:
an audio transmission and reception circuit, linked to the transmitter and to the receiver by an analog link,a non-erasable memory comprising a digital encryption key,an erasable read-only memory,a digital communication interface, configured to transmit or receive digital signals between the outside of the device and the audio circuit, the non-erasable memory and the erasable read-only memory.
