PW254 Germicidal Lamp Detector

Solar Light’s PW254, germicidal lamp monitor, is specifically designed to continuously monitor UV intensity from UVC lamps in a high pressure water disinfection tank (reactor). The sensor provides an indication of the effectiveness of the lamps as they age because it is sensitive to the sterilizing UVC wavelengths of mercury lamps at 253.7nm. The sensor reliably interfaces with the Solar Light GLM100 germicidal lamp monitor, or your choice of monitor or data acquisition equipment. Its output is a standard 4-20 mA and the sensor screws into the service port of the water disinfection tank. The screw thread is supplied for 1×11.5″FPT.

UV water disinfection systems are only as good as the effectiveness of the germicidal lamps. With time, even the best UV water treatment system will show a significant degradation in its ability to disinfect water. Germicidal lamp output decreases as the lamp ages and/or becomes dirty through use.
