<p>TEMPERATURE SENSORS WITH IMPROVED OPERATING CHARACTERISTICS UTILIZING MAGNETIC ELEMENTS Temperature sensors utilizing either one pair or two pair of inductive magnetic elements are disclosed. The inductive elements of each pair are constructed of different magnetic materials so that the permeability of the two elements change at different rates with respect to temperature. A plot of inductance vs. temperature for the two elements, thus, provides curves which intersect at the temperature which is to be sensed. Permanent magnets are positioned adjacent the temperature sensing elements in order to provide a mechanism for adjusting the cross-over temperature point of the magnetic elements.</p> |
