Mar 11, 2009 Based on Thick Film on Steel technology (WDBR), resistive heating elements on insulated stainless steel substrates enable use of intrinsically safe, flameproof planar device that can be formed in any flat shape to deliver precision heating control in sensitive medical applications. Fuses and thermistors can be integrated directly into heating elements to provide additional over-temperature protection as well as closed-loop feedback control.

Aug 12, 2003 Kanthal Globar® SD silicon carbide heating element is extruded from blend of high-purity alpha silicon carbide grain, which is recrystallized at over 2,500°C to form self bonded structure. Manufactured in one- or 3-piece construction, products may be supplied as straight rods or multi-leg elements. Low porosity and large grain size reduce total surface area of silicon carbide that is exposed to furnace atmosphere, which reduces rate of resistance increase over time.
