KIPP ZONEN Rt1 Solar Irradiance Measurement Table

-KIPP ZONEN Rt1 Solar Irradiance Measurement TableWorking Principle:

The RT1 instrument is a high-quality radiometer used to measure the solar irradiance (radiation flux, W/m2) on a flat surface, which is caused by the sum of direct solar radiation and direct sky radiation above the instrument.

-KIPP ZONEN Rt1 Solar Irradiance Measurement TableInstrument features:

RT1 has internal digital signal processing and an interface system optimized for industrial data acquisition and control. Kipp&Zonen has developed an intelligent interface with RS-485 Modbus for connection ® Programmable Logic Controllers (PLCs), inverters, digital control devices, and next-generation data loggers for data communication. Digital signal processing provides faster response times and corrects the sensitivity dependence of temperature detectors through integrated temperature sensors. In order to achieve the required low directional error when the sun is below the horizon, RT1 also uses a special user interface that improves its resistance to pollution as most dust and dirt only move or flow. RT1 is equipped with a waterproof plug that can be pre connected to a 20 meter long, high-quality signal cable and a 3-meter temperature strip sensor for PV panels. The RT1 distributed monitoring system uses a calibrated sunshine intensity meter according to Appendix A.3 for calibration. ISO 9847 'calibrates the field celestial radiometer by comparing it with a reference sunshine intensity meter'. Calibration can be traced back to the World Radiometric Reference (WRR) in Davos, Switzerland. Detailed information can be found on the accompanying calibration certificate for each instrument.
