Abstract

A multiple temperature autoregulating heater compris­ es a laminate of a conductive material, a first ferromagnetic layer on a surface of the conductive material and a second ferromagnetic layer insulated from the first layer. The lay­ ers have different Curie temperatures. A switching device is provided to connect one or the other of the layers to be en­ ergized from a constant current source. The device auto­ regulates in the region of the Curie temperature of the se­ lected layer. The conductive material may be non-magnetic (copper) or a low resistivity ferromagnetic material having a Curie temperature well above the Curie temperatures of the autoregulating layers. In the latter case, a thin layer of copper or the like may be interposed between the surface and the conductive ferromagnetic material to further inc­ rease conductivity. The device may be provided with mul­ tiple ferromagnetic layers to provide multiple different auto­ regulating temperatures.
