digital DVGW compliant UV Sensor with RS485 (ModBus/ZCON)


  • sensors are intended for use in certified systems in compliance to
    - German standard DVGW W294
    - Austrian standards ÖNORM M5873-1 and Vornorm ÖNORM M5873-2 The D-SiCONORM sensors are certified by an ÖNORM accredited laboratory.
  • Note: According to DVGW/ÖNORM these UV-sensors are to be used with a measurement window (e.g. ZED MF001) to allow the demanded calibration checks; ZED offers a sensor recalibration service.
  • 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
