UV transmittance monitor

Sensorex has announced the UVT-LED-PW Transmittance Monitor, which provides continuous monitoring for accurate UV disinfection dosing. The compact monitor delivers fast, accurate, in-line transmittance readings in industrial process and drinking water settings where UV disinfection is used. Patented automatic wiping and calibration mechanisms significantly reduce maintenance burden and extend service life, according to the company.

The product is mounted directly in a pressurised pipe or sampling line, taking automatic measurements every 60 seconds. The sensor directly outputs a 4-20mA signal for UV system control or data logging.

Furthermore, the integrated Teflon wiper delivers a swift cleaning cycle before each reading is taken, to prevent fouling and build-up in water and wastewater applications. The sensor automatically calibrates to a quartz reference standard built into the wiper mechanism. These integrated features, along with highly efficient UV-C LED lamps, reduce maintenance and significantly lower operating expenses related to UVT monitoring and UV disinfection, according to the company.
