Abstract
An improved apparatus including a thermocouple for measuring the temperature in a gasification process is provided. The improvement includes a sapphire reinforced outer protection tube for enclosing at least a portion of the thermocouple. The sapphire reinforced outer protection tube may be integrally formed around an inner protection tube, the inner protection tube being receptive of a sapphire-sheathed thermocouple. The apparatus may be inserted directly into a gasification stream without the use of a thermowell. The sapphire reinforced outer protection tube increases the life of the thermocouples used in gasification processes.
