A sensor for measuring a physical parameter of a fluid, in particular for measuring total air temperature, the sensor comprising: a fluid intake () fitted to a streamlined body (); a duct provided in said streamlined body () to enable fluid flow, said duct communicating with said fluid intake; and a sensing element disposed inside said duct. The sensor is characterized in that it includes elements that give it improved measurement performance. In particular, the proposed air intake presents an inlet section which extends so as to define a sliding surface suitable for eliminating ice. The invention also provides an improved system for sucking in the boundary layer by using slots, and it also provides a ceramic sensing element that provides better thermal decoupling relative to the de-iced body.

De-iced total air temperature sensor

Ice detection assembly () designed for installation on an aircraft, comprising a vibrating finger () and a mast (), the vibrating finger () extending into the air from the mast () and capable of being vibrated by vibration means at a resonant frequency that is sensitive to an ice deposit on its surface, characterised in that it comprises a cooling system capable of cooling at least part of the detection assembly ().

The invention concerns a mass flow meter comprising at least a resistive wire ( or ) placed in the path of a fluid whereof the flow rate is to be measured, means ( ) for applying to the wire current pulses, measuring means for determining the cooling speed of the wire between said pulses. The invention is characterised in that it comprises means for determining, on the basis of at least one measurement of the cooling speed, the type of fluid on the path of which the resistive wire is arranged.
