ABSTRACT:
The ultraviolet sensing device disclosed herein employs a visible light sensitive photoconductive cell which is protected from direct exposure to ultraviolet light by a housing. Ultraviolet light entering the housing through a quartz window illuminates a fluorescent material and the photoconductive cell is oriented so as to receive visible light given off by the fluorescent material while being shielded from the direct ultraviolet rays.
