Abstract

A de-icing unit 7 for an air pressure sensor intended for use on aircraft comprises a carrier member 8 with a coaxial air pressure line 5 running through it, the carrier member supporting at least one annular PTC heating element 9. The heating elements are constrained by a flange 11 formed on the carrier so that heat is conducted into the carrier warming the air in the line. The mouth 4 of the line opens into the mass of air to be measured. The other end 20 leads to a pressure sensor (not shown). Current is supplied to the elements via connections (15a, b, figure 1b). The elements and connections are secured to the carrier by a nut 14. The elements are surrounded by a casting compound 19, within housing 2.
