Transmittance Sensor

Sensorex offers the UVT-LED-SW UV Transmittance Sensor that provides continuous monitoring for accurate UV disinfection dosing. The probe delivers fast, accurate, UV transmittance readings in open channel wastewater treatment applications where UV disinfection is used. With proper dosing adjustment based on UVT values, fluctuations in organic content can be accounted for and UV disinfection energy efficiency is increased.  The UVT-LED-SW is mounted directly to the wall of any open channel system, taking automatic measurements every 60 seconds. The sensor directly outputs a 4-20mA signal, integrating into a variety of process monitoring systems without a transmitter or controller. Patented cleaning and calibration features ensure UVT-LED-SW measurements are accurate and reliable. The integrated Teflon wiper delivers a swift cleaning cycle before each reading is taken, preventing fouling and build-up. At the same time, the sensor self-calibrates to an integrated quartz reference standard. Sensorex offers several installation kits, including mounting hardware for new installations and retrofits of Hach UVAS models. The UVT-LED-SW is also compatible with Hach SC200 controllers for retrofit installation.
