ABSTRACT:
A signaling gauge may utilize a magnetically actuated variable resistor made up of a plurality of noncaptivating, magnetically actuated switch elements, each of which is mounted in an influence zone of a path of a magnet carried on an arm of a condition sensor such as a gauge movement. The arm may be an indicating pointer of the gauge. The gauge may alternatively utilize a magnetically-sensitive, variable-resistance element in a contactless arrangement with a magnet. The variable resistance element may include a plurality of noncaptivating, magnetically actuated switch elements and associated resistors mounted in an influence zone of a path of a magnet. The contactless arrangement eliminates the need for electromechanical contacts.
