ABSTRACT:
A system for measuring the temperature of the walls of a metallurgical furnace employs a temperature measuring rod mounted for reciprocal movement in an aperture in the furnace wall from an extended position projecting into the interior of the furnace to a withdrawn position. Cyclic reciprocating movement is imparted to the rod by an actuating mechanism, mounted on the furnace wall and including a double acting fluid motor and a servomechanism. The actuating device includes an articulated mounting mechanism permitting the device to be positioned by pivotal movement about two mutually perpendicular axes whereby alignment difficulties on rebuilding the furnace wall are eliminated. Means are also provided for quickly disconnecting the servomechanism to facilitate manual positioning of the measuring rod.
