Abstract
An ultraviolet sensor monitors an effectiveness of ultraviolet lamps used in sterilization systems. The sensor includes an ultraviolet photodetector and a filter cooperating therewith configured for detecting light at wavelengths between 200-300 nm. A purification system for air or water utilizes the sensor in conjunction with an ultraviolet lamp directing ultraviolet light toward the air or water.
Claims24
An ultraviolet sensor for monitoring energy in predetermined wavelengths for sterilizing microorganisms, the sensor comprising:
- an ultraviolet photodetector sensitive to a broad range of ultraviolet light;
- and
- a filter disposed in a position to intercept light directed toward the ultraviolet photodetector, the filter being configured to block light at wavelengths outside of said predetermined wavelengths.
An ultraviolet sensor for monitoring an effectiveness of ultraviolet lamps used in sterilization systems, the ultraviolet sensor comprising an ultraviolet photodetector and a filter cooperating therewith configured for detecting light at wavelengths between 200-300 nm.
A purification system for air or water comprising:
- an ultraviolet lamp directing ultraviolet light toward the air or water;
- an ultraviolet sensor for monitoring an effectiveness the ultraviolet lamp in predetermined wavelengths, the ultraviolet sensor comprising an ultraviolet photodetector sensitive to a broad range of ultraviolet light, and a filter disposed in a position to intercept light directed toward the ultraviolet photodetector, the filter being configured to block light at wavelengths outside of said predetermined wavelengths.
A method of purifying air or water comprising:
