Abstract
An ultraviolet radiation sensor for use in a liquid purification system senses ultraviolet radiation present in an incident beam containing ultraviolet and visible radiation and includes a beamsplitter which reflects ultraviolet radiation and transmits visible radiation. The reflected ultraviolet radiation impinges on a glass plate having a phosphor layer which emits visible radiation. The visible radiation emitted impinges on a photocell which is connected to an electrical meter and thereby provides a measure of the ultraviolet radiation present. The visible radiation transmitted through the beamsplitter enables visual monitoring of a source of radiation while simultaneous ultraviolet measurements are made.
