ABSTRACT:
Cleansing of a pyrometer lens is achieved by directing purge air spirally inward over the lens surface. The vortex formed by the spiral air flow is highly effective in removing contaminating matter from the lens surface. A light blocking or masking element is attached to the center of the lens where the purge air stagnates to prevent deposit of particles or other material on the center portion of the lens. This invention relates to a temperature sensing device and, more particularly, to an optical pyrometer and a method for effectively cleaning the same.
