Abstract

Probe for determining the temperatures of the walls of coke oven flues, including an optical pyrometer suspended by a metallic rope from a manipulating device including a drum on which the rope is coiled and uncoiled. The pyrometer is contained in an insulating sleeve of refractory material, and the rope is surrounded by a sheath which is wetted before the measurement takes place, in order to prevent an unacceptable temperature rise during the brief measurement period required. Due to this arrangement, conventional cooling apparatus is eliminated.
