UV-C sensor with lateral UV detection and digital interface


  • sensors are intended for monitoring UV lamps in water/air purification and disinfection systems
  • detecting relative UV irradiance values
  • UV values are indicated in "%" with the appropriate UV-monitor
  • Positioned in a quartz tube in the centre of the circular lamp array they allow lateral "side-looking" detection of UV-C irradiation between the lamps of an reactor
  • sensors cover the intensity range for low pressure application and incorporate an automated measuring range selection.
  • due to the digital processsing the signal transmission is fail safe regardless of the cable length (max. 30m)
  • connection of additional sensors to the RS485 bus allows multi sensor operation
  • ModBus UV sensor types for connection to PLC are available on request
