Digital 1/4 Inch UV Sensor  with RS485 (ModBus/ZCON)


  • sensors for monitoring UV lamps in water/air purification and disinfection systems
  • detecting absolute UV irradiance values
  • UV values are indicated in "W/m²", "mW/cm²" or "%" with the appropriate UV-monitor
  • available for low pressure and medium pressure applications
  • All digital UV-sensors are adjusted to cover the complete specified measurement range

  • - low pressure types: range 2...500W/m²

  • - medium pressure types: range 20...3000W/m²

  • - customized ranges are available on request
  • connection of additional sensors to the RS485 bus allows multi sensor operation
  • for use with ZED controllers, UV monitors and UV measurement
  • for use with PLC via RS485/ModBus RTU
