  • Temperature probe with sapphire thermowell
    Patent number: 6059453
    Abstract: A temperature probe for measuring temperatures in a fluid contains a temperature responsive electrical element partially encased by a sapphire encasement. The sapphire encasement and the electrical element are further partially encased by a ceramic encasement that is exposed to the fluid. The ceramic encasement is permeable to certain gases to which the sapphire encasement is impermeable. A series of seals in the temperature probe prevents fluid from exiting through the temperature probe if the ceramic encasement and sapphire encasement are breached.
