UV-C Reference Sensors for checking ÖNORM compliant plant sensors

Features

  • sensors are intended for UV-C intensity reference measurement for checking sensors in ÖNORM/DVGW compliant systems
  • According to DVGW W294 and ÖNORM M 5873-1, annual calibration checks of the plant sensors are required. For this purpose the reference sensor is placed on the measurement position of the plant sensor and both measured values are compared with each other.
  • digital Reference Sensors are calibrated irrespective of the desired displaying system
  • measured values are internally converted into a digital signal according to ZEDs special ZCON protocol
  • via RS485 this signal can be visualized using a suitable displaying system like the ZED SmartMeter or the PC software ZED Sensor Configurator
  • combination of a Reference Sensor with a displaying system is the ZED Reference Radiometer
  • sensor must be sent to the manufacturer for periodic inspection and recalibration
  • recalibration of the displaying system is not necessary
  • ÖNORM reference sensors are available for the intensity ranges 0.01...250W/m² and 0.1...500W/m²

Technical Specification

supply voltage: 12...24V DC
sensitive element: silicon carbide diode (SiC)
