Transition Temperature Rating:

  • Standard transition is rated to 482°F (250°C).
  • Optional High Temperature Transition is rated to 842°F (450°C).
  • Standard heater lead wire insulation is TGGT (Teflon®, double fiberglass, Teflon® impregnation), which is rated to 482°F (250°C).
  • Optional high temperature insulation is MGT (mica, fiberglass, Teflon® impregnation) which is rated to 842°F (450°C).

Thermocouple:

  • Standard leads use a fiberglass insulation rated to 900°F (482°C).
  • Teflon® insulation is available upon request.

Optional lead protection: Stainless steel overbraid or galvanized armor cable.
