Sensorex Expands UV Transmittance Offerings with Submersible Sensor

UVT-LED-SW delivers efficient, accurate UV transmittance monitoring for municipal wastewater applications

The UVT-LED-SW UV Transmittance Sensor 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.

The unit’s highly efficient UV-C LED lamps provide up to five times longer life than comparable mercury lamps, eliminating field-serviceable parts. All of these features reduce maintenance and significantly lower operating expenses related to UVT monitoring and UV disinfection. No costly service and maintenance contracts are required; all maintenance can be performed onsite.

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.

The submersible UVT sensor is the third product in the Sensorex UVT-LED family. It joins the UVT-LED-PW, an in-line UVT monitor that can be mounted directly in a pressurized pipe or sampling line, and the UVT-LED-H, a lightweight, battery operated, handheld UVT monitor ideal for sample measurements in the field, as well as periodic verification of calibration of online UVT analyzers.
