High temperature sensor sleeve

A high temperature sensor housing adapted for mechanical insertion of a sensor into a hole formed in a monitored system and sealed attachment to the monitored system, the high temperature sensor housing comprising:

• a sensor housing comprised of low coefficient of thermal expansion material formed in a sleeve-like configuration having an inner surface and outer surface, the sensor housing providing thermal insulation to a sensor held within center formed by the inner surface of the sensor housing;
• an metal housing also formed in a sleeve-like configuration and having a threaded outer surface and an inner surface, wherein the inner surface of the metal housing is fused with the outer surface of the sensor housing;
• and
• a metal flange formed in a hex nut-like configuration and integrated with the metal housing, wherein the integrated metal flange enables mechanical insertion of the metal housing and a sensor held within the sensor housing and exposed inside the monitored system into the hole formed in the monitored system and wherein the hole formed in the system includes complimentary threading for securely retaining the metal housing by its threaded outer surface.

A method of fabricating a high temperature sensor housing, the method comprising:

• providing a low coefficient of thermal expansion material and forming it into a sleeve-like housing having an inner surface that creates a void for placement of a sensing component;
• providing a metal housing and forming it into a sleeve-like housing having an inner surface and external surface;
• welding the outer surface of the sensor housing and the inner surface of the metal housing wherein the surfaces become fused together while providing for structural, electrical and sealing needs of a monitored system;
• forming a mechanical interface on the outer surface of the metal housing, said mechanical interface for securing the sensor housing and sensing component held within the sensor housing to be securely held within a sensed system through a hole formed in a wall associated with the sensed system.
