Abstract
A conductive heat transfer mechanism through which energy readily flows between two bodies or systems at different temperatures. The present mechanism is embodied in a temperature sensing network for determining and controlling the surface temperature of a xerographic fuser roll. The network includes a probe shoe containing at least one temperature sensing element with the shoe being positioned in close non-contiguous relation with the moving surface of a heated fuser roll. A magnetic flux field is created within the air gap between the heated roll surface and the probe shoe and a magnetic medium, preferably being in fluid form, having a relatively high coefficient of thermal conductivity is placed within the flux field through which a rapid and efficient flow of heat is maintained.
