  • High output and environmentally impervious variable reluctance sensor
    Patent number: 5998988
    Abstract: A variable reluctance sensor assembly including an open-ended housing which contains a bobbin assembly with an overmolded connector piece. The bobbin contains a ferrous pole piece pressed into a closed-ended cavity within the bobbin, a small disc-shaped rare earth permanent magnet mounted forward of the pole piece, and a magnet wire coil wound upon the bobbin barrel and attached to the customer terminals which carry the output signal. A separate submersible connector is affixed to the integral connector. A front seal ring is stretch fit to the forward flange of the bobbin, and a rear seal ring is stretch fit to the rear section of the sensor housing. The bobbin assembly is slip fit into the housing with magnet forward.
    Type: Grant

  • Method of assembly of a variable reluctance sensor
    Patent number: 5507089
    Abstract: A method of securing the bobbin assembly of a variable reluctance sensor within a hollow sensor shell having an opening in the front wall thereof to permit the magnet of the bobbin assembly to be exposed therethrough. A welding apparatus is provided for automatically ultrasonically welding the rear portion of the bobbin assembly to the open rear end portion of the shell, thereby preventing fluid flow through the rear end of the shell. The welding process forces the bobbin assembly into the sensor shell sufficiently to compress the front elastomeric seal between the front flange of the bobbin assembly and the inner surface of the front wall of the shell.
