## Abstract

A probe for measuring static or parietal pressure includes a pressure sensor module, a mounting plate equipped with air inlets which is intended to be mounted on the skin of an aircraft, and a shut-off means equipped with shut-off fingers which are configured to plug the air inlets of the mounting plate, and an actuator, controlled by a control module, configured to move the shut-off means in a translational movement so as to plug or unplug the air inlets of the mounting plate by the shut-off fingers.

## Claims

### Claim 1

A probe for measuring static or parietal pressure comprising a pressure sensor module, a mounting plate equipped with air inlets which is intended to be mounted on the skin of an aircraft, and a piston equipped with shut-off fingers which are configured to plug the air inlets of the mounting plate, and an actuator, controlled by a control module, configured to move the piston in a translational movement so as to plug or unplug the air inlets of the mounting plate by the shut-off fingers.

### Claim 2 (depends on 1)

The probe for measuring pressure as claimed in claim 1, wherein the control module comprises an electronic control board.

### Claim 3 (depends on 1)

The probe for measuring pressure as claimed in claim 1, comprising an indexing device, and wherein the piston comprises a slot intended to receive one end of the indexing device so as to prevent the piston from rotating during its translational movement.

### Claim 4 (depends on 1)

The probe for measuring pressure as claimed in claim 1, wherein the piston comprises an annular seal arranged on the upper part of the shut-off means.

### Claim 5 (depends on 1)

The probe for measuring pressure as claimed in claim 1, wherein the piston comprises an annular wiper seal arranged on the lower part of the shut-off means.

### Claim 6 (depends on 1)

The probe for measuring pressure as claimed in claim 1, wherein the piston is equipped with a reservoir for storing water and contaminants.

### Claim 7 (depends on 1)

The probe for measuring pressure as claimed in claim 1, wherein a shut-off finger comprises an annular part made of elastomer arranged at the periphery of the shut-off finger.

### Claim 8 (depends on 7)

The probe for measuring pressure as claimed in claim 7, wherein the reservoir is a blind hole in the underside face of the piston.

### Claim 9 (depends on 1)

The probe for measuring pressure as claimed in claim 1, comprising an external cap.

### Claim 10 (depends on 1)

The probe for measuring pressure as claimed in claim 1, comprising a supporting structure supporting the mounting plate, the pressure sensor module, the piston, the actuator, the control module that controls the sensor, the indexing device, the O-ring seal, the wiper seal and the cap.
