Tolerances
The diameter and "out of roundness" of OMEGA's insulators is plus or minus 5% or ±0.015", whichever is greater. The straightness is at least 1/32 inch for each six-inch length. The following table lists the maximum recommended wire diameters which should be used with six-inch sections. Closer tolerances are permissible with shorter sections, but the minimum clearance tolerance is ±5% or 0.015 inch, whichever is greater.

OMEGATITE™ 450
This is an impervious, recrystallized, pure alumina ceramic containing over 99.8% Al2O3. It has the most superior gas and vacuum tightness and electrical insulating properties at elevated temperatures. It is non-reactive and recommended for use with platinum, as well as tungsten and molybdenum thermocouple alloys. The maximum service temperature is 1900°C (3450°F).

OMEGATITE™ 350
This is an impervious, recrystallized pure alumina ceramic containing over 99% Al2O3. It has superior gas and vacuum tightness and electrical insulating properties at elevated temperatures. It is non-reactive and compatible with tungsten and molybdenum thermocouple alloys. The maximum service temperature is 1900°C (3450°F).

OMEGATITE™ 200
This material is recommended for most thermocouple applications. It consists of a mullite type ceramic capable of withstanding temperatures up to 1650°C (3000°F).
