SMP3 Pyranometer

The SMP3 is a smart pyranometer with low maintenance and industry standard digital and analogue amplified outputs. Based on the proven CMP 3 technology the SMP3 adds Modbus® interface, improved response time and temperature corrected measurement data. The wide and low power supply range from 5 to 30 VDC makes integration in meteorological stations easy. The SMP is protected against over voltage, reversed polarity and short circuiting. Because all SMP’s have identical sensitivity and connections exchanging instruments during recalibration is easy.

SmartExplorer Windows™ for data logging, display of data and Modbus® address setting is provided as standard.

SMP3 measures global solar radiation on a horizontal plane. When tilted with the same angle as a PV panel it measures the tilted global radiation, for PV module efficiency calculations.

  • What type of pyranometer can I use for my fixed PV panels farm?
    • For this application the CMP10 and SMP10 are advised as they have an internal drying cartridge that will last for at least 10 years.

      Please note that the pyranometer needs to be mounted in the same angle (POA) as the PV panel. 


      For users that prefer the desiccant visible Kipp & Zonen offers the CMP11 and SMP11 with visible and user changeable desiccant.
