Digital UV-Sensors with RS485 interface back
  • The sensors are intended for monitoring UV lamps in water/air purification and disinfection systems
    for detecting absolute UV irradiance values. (UV values are indicated in "W/m²", "mW/cm²" or "%" with the appropriate UV-monitor)
  • The D-SiCDVGW/D-SICONORM types 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.
  • All digital UV-sensors are adjusted to cover the complete specified measurement range.
    One sensor can be used for all applications:
    • low pressure types: range 2...500W/m²
    • medium pressure types: range 20...3000W/m²
    • customized ranges are available on request
  • Due to the digital processsing the signal transmission is fail safe regardless of the cable length (max. 30m).
  • The connection of additional sensors to the RS485 bus allows multi sensor operation.
    ZED offers several monitor types for simultaneous monitoring of 2 to 4 UV sensors. Larger numbers of sensors might be connected in parallel via RS485 to a PLC and evaluated via ModBus.
  • ZED SmartMeter and PC Software Sensor Configurator are available
    • to display and log measurement values
    • for sensor setup (e.g. select protocol type and set ModBus address)
    • for reference check
  • The measurement window MF001 is intended for mounting DVGW/ÖNORM compliant UV-Sensors in certified UV systems. The measurement window adpater MF001-A allows the adaptation of the 1/4 inch sensor types D-SiC131/D-SiCT141 to reactors with threads for measurement window MF001 (ISO228 G1 inch).
