1. A device for measuring the characteristics of an air flow of an annular stream of a turbomachine, the device comprising:
a rod extending along a first axis and carrying means for measuring the characteristics of an air flow and sealingly slidingly engaged in a first tubular part extending into a second tubular part passing sealingly along the first axis through a slider mounted slidingly in a slide along a second axis perpendicular to said first axis, said rod being engaged with an annular clearance in said second tubular part;
wherein the first tubular part comprises a first support plate supporting, in rotation about the first axis, a first actuator for translational displacement of the rod along said first axis, the first support plate comprising a circuit capable of allowing air circulation and configured to be connected to air supply means.
