This construction was developed to operate in extreme applications to withstand continuous
temperatures as high as 2200°F (1204°C). Ceramic is being used under
conditions where beaded ceramic or sheathed thermocouples previously were
necessary. Because the insulation retains it's overall product integrity
at these elevated temperatures, it increases serviceability while reducing
replacement and maintenance costs.
Ceramic construction contains the single conductors insulated
with an aluminaboric-silica fiber braid. The singles are laid parallel and
jacketed with the same material. Ceramic is flexible, and offers good
abrasion and chemical resistance. The insulation contains no residual
acids or chlorides to leach out and cause etching of the wires.
For detailed information on the various thermocouple types, insulation properties, gauge sizes, and wire weights see our Technical Data catalog.
