Abstract
A gauge assembly is provided including a bobbin assembly disposed within a housing. A magnetic armature is rotatably supported within a sealed chamber defined by said bobbin assembly. Three independent wire coils are wrapped around the bobbin assembly within three separate coil cavities defined by the bobbin assembly.
Claims13
A gauge assembly, comprising:
- a housing;
- a bobbin assembly having three coil cavities defining an equilateral triangle supported within said housing, said bobbin assembly including first and second bobbin elements which engage one another to define a generally cylindrical sealed chamber;
- an armature supported within said chamber by a spindle which extends through an opening in one of said first and second bobbin elements wherein a tangent point of said armature is located at a centroid of each of said coils;
- and
- three wire coils wound over said bobbin assembly, each wire coil having two ends each terminating at respective terminals.
