Abstract
A hub mountable speed sensing device comprising a housing, a metallic tubular insert adapted to be press-fitted with respect to said housing, a stationary speed sensing probe comprising a magnetic conversion device having a bias magnet and adapted to be inserted into the housing in close proximity to a rotating member having sensing teeth along its axis made of ferrous material, a locking arrangement provided to prevent the said detection probe from dislodging from said housing, and wherein the said bias magnet is adapted to generate magnetic flux which is interrupted by the rotor tooth while rotating and said magnetic conversion device providing for speed sensing based on the change in flux density.

A hub mountable speed sensing device comprising:
- a housing;
- a metallic tubular insert adapted for securedly supporting thereon a rotatable metal wheel and also to be press fitted with respect to said housing;
- a stationary speed sensing/rotation detection probe comprising a magnetic conversion device having a bias magnet and adapted to be inserted into the housing in close proximity to said rotating metal wheel mounted on said metallic tubular insert and having sensing teeth along its axis made of ferrous material;
- a locking arrangement provided to prevent the said detection probe from dislodging from said housing;
- and
- wherein the said bias magnet is adapted to generate magnetic flux which is interrupted by the said teeth of said rotatable metal wheel while rotating and said magnetic conversion device providing for speed sensing based on the change in flux density.
