Abstract

A sealing assembly 7 comprises two rigid connectable screens 8,9 one of which is provided with an elastomeric sealing element 23 cooperating with the other screen 8, one of the screens being fixedly provided with a sensor 22 (magnetic, inductive, capacitive) whilst the other is provided fixedly with a ferromagnetic reference element 19 provided with a plurality of depressions 18 at regular intervals in a ring, for example a toothed element. The screen 8 provided with the toothed element is securely fitted onto a rotating member the speed of which it is desired to measure, for example on a flanged ring 2 of a rolling element bearing fixed securely to the wheel of a vehicle, whilst the other screen 9 is fitted onto the other member, for example the other ring 3 of the said bearing, in such a way as to define with the said members a chamber 24 housing the sensor 22 and the ferromagnetic element and closed in a fluid tight manner against the exterior by the elastomeric element 23.
